e01b1eb289 cmd/compile/internal: stack slot merging region formation enhancements
This patch revises the algorithm/strategy used for overlapping the
stack slots of disjointly accessed local variables. The main change
here is to allow merging the stack slot of B into the slot for A if
B's size is less then A (prior to this they had to be identical), and
to also allow merging a non-pointer variables into pointer-variable
slots.

The new algorithm sorts the candidate list first by pointerness
(pointer variables first), then by alignment, then by size, and
finally by name. We no longer check that two variables have the same
GC shape before merging: since it should never be the case that we
have two vars X and Y both live across a given callsite where X and Y
share a stack slot, their gc shape doesn't matter.

Doing things this new way increases the total number of bytes saved
(across all functions) from 91256 to 124336 for the sweet benchmarks.

Updates #62737.
Updates #65532.
Updates #65495.

a973b4256e cmd/dist: allow arbitrary package renames for bootstrap imports
Import declaration matching currently has a list of specific cases. It
allows bare imports, dot imports, and renamed imports named "exec" and
"rtabi".

Keeping a specific allowlist of renamed imports is unnecessary and
causes annoyance for developers adding such imports, as the bootstrap
build errors do not make it clear that this is where the issue lies.

We can simplify this to be much more general. The body of the condition
will still only rewrite imports in cmd/ or in bootstrapDirs.

I believe the only downside of this change is that it makes it a bit
more likely to match and replace within comments. That said, there
should be no harm in replacements within comments.

This change results in no change to the resulting bootstrap source tree:

84fbdf01ff cmd/go: use cache for PGO preprocessing
This is the final CL in the series adding PGO preprocessing support to
cmd/go. Now that the tool is hooked up, we integrate with the build
cache to cache the result.

This is fairly straightforward. One difference is that the compile and
link do caching through updateBuildID. However, preprocessed PGO files
don't have a build ID, so it doesn't make much sense to hack our way
through that function when it is simple to just add to the cache
ourselves.

As as aside, we could add a build ID to the preproccessed file format,
though it is not clear if it is worthwhile. The one place a build ID
could be used is in buildActionID, which currently compute the file hash
of the preprocessed profile. With a build ID it could simply read the
build ID. This would save one complete read of the file per build
(cmd/go caches the hash), but each compile process also reads the entire
file, so this is a small change overall.

Fixes #58102.

4084bc1aa2 cmd/go: inital plumbing for PGO profiles preprocessing
The new go tool preprofile preprocesses a PGO pprof profile into an
intermediate representation that is more efficient for the compiler to
consume. Performing preprocessing avoids having every single compile
process from duplicating the same processing.

This CL prepares the initial plumbing to support automatic preprocessing
by cmd/go.

Each compile action takes a new dependency on a new "preprocess PGO
profile" action. The same action instance is shared by all compile
actions (assuming they have the same input profile), so the action only
executes once.

Builder.build retrieves the file to pass to -pgofile from the output of
the preprocessing action, rather than directly from
p.Internal.PGOProfile.

Builder.buildActionID also uses the preprocess output as the PGO
component of the cache key, rather than the original source. This
doesn't matter for normal toolchain releases, as the two files are
semantically equivalent, but it is useful for correct cache invalidation
in development. For example, if _only_ go tool preprofile changes
(potentially changing the output), then we must regenerate the output
and then rebuild all packages.

This CL does not actually invoke go tool preprocess. That will come in
the next CL. For now, it just copies the input pprof profile.

This CL shouldn't be submitted on its own, only with the children. Since
the new action doesn't yet use the build cache, every build (even fully
cached builds) unconditionally run the PGO action.

For #58102.

9101bf1916 go/types, types2: use types2.Config flag to control Alias node creation
Move Checker.enableAlias to Config.EnableAlias (for types2) and
Config._EnableAlias (for go/types), and adjust all uses.

Use Config.EnableAlias to control Alias creation for types2 and
with that remove dependencies on the gotypesalias GODEBUG setting
and problems during bootstrap. The only client is the compiler and
there we simply use the desired configuration; it is undesirable
for the compiler to be dependent on gotypesalias.

Use the gotypesalias GODEBUG setting to control Config._EnableAlias
for go/types (similar to before).

Adjust some related code. We plan to remove gotypesalias eventually
which will remove some of the new discrepancies between types2 and
go/types again.

Fixes #66874.

334ce51004 net/http: don't cancel Dials when requests are canceled
Currently, when a Transport creates a new connection for a request,
it uses the request's Context to make the Dial. If a request
times out or is canceled before a Dial completes, the Dial is
canceled.

Change this so that the lifetime of a Dial call is not bound
by the request that originated it.

This change avoids a scenario where a Transport can start and
then cancel many Dial calls in rapid succession:

  - Request starts a Dial.
  - A previous request completes, making its connection available.
  - The new request uses the now-idle connection, and completes.
  - The request Context is canceled, and the Dial is aborted.

Fixes #59017

4742c52e10 internal/abi: define EmptyInterface, TypeOf, and NoEscape
This change defines two commonly-defined functions and a
commonly-defined type in internal/abi to try and deduplicate some
definitions. This is motivated by a follow-up CL which will want access
to TypeOf in yet another package.

There still exist duplicate definitions of all three of these things in
the runtime, and this CL doesn't try to handle that yet. There are far
too many uses in the runtime to handle manually in a way that feels
comfortable; automated refactoring will help.

c686783cab cmd/compile/internal/ssa: delay rewrite cycle detection for huge funcs
The SSA rewrite pass has some logic that looks to see whether a
suspiciously large number of rewrites is happening, and if so, turns
on logic to try to detect rewrite cycles. The cycle detection logic is
quite expensive (hashes the entire function), meaning that for very
large functions we might get a successful compilation in a minute or
two with no cycle detection, but take a couple of hours once cycle
detection kicks in.

This patch moves from a fixed limit of 1000 iterations to a limit set
partially based on the size of the function (meaning that we'll wait
longer before turning cycle detection for a large func).

Fixes #66773.

15cec430d7 types2: flip the default value of GODEBUG=gotypesalias=1
This CL changes the interpretation of the unset value
of gotypesalias to not equal "0".

This is a port of CL 577715 from go/types to types2,
with adjustments to go/types to keep the source code
in sync. Specifically:

- Re-introduce testing of both modes (gotypesalias=0,
  gotypesalias=1) in go/types.
- Re-introduce setting of gotypesalias in some of the
  tests for explicit documentation in go/types.

The compiler still uses the (now) non-default setting
due to a panic with the default setting that needs to
be debugged.

Also, the type checkers still don't call IncNonDefault
when the non-default setting of gotypesalias is used.

1488bb6c4c cmd/cgo: create -objdir if not exist
Currently the directory is created only if -objdir is omited.
Creating the directory here is useful to avoid doing this in each build system.
And also this is consistent with similar flags of other tools like `-o`.

ca94e9e223 os: make File.Readdir et al concurrency-safe
Before, all methods of File (including Close) were
safe for concurrent use (I checked), except the three
variants of ReadDir.

This change makes the ReadDir operations
atomic too, and documents explicitly that all methods
of File have this property, which was already implied
by the package documentation.

cf760ce29c go/types: flip the default value of GODEBUG=gotypesalias=1
This CL changes the interpretation of the unset value
of gotypesalias to equal "1". The actual deletion of
all the transitional logic will happen in a follow-up.

Note that the compiler still interprets unset as "0".
More work appears to be required within the compiler
before it is safe to flip its default.

f7f56ded01 cmd/internal/obj/loong64: recheck jump offset boundary after auto-aligning loop heads
After the alignment of the loop header is performed, the offset of the checked
conditional branch instruction may overflow, so it needs to be checked again.

When checking whether the offset of the branch jump instruction overflows, it
can be classified and processed according to the range of the immediate field
of the specific instruction, which can reduce the introduction of unnecessary
jump instructions.
