Normally, the HTTP/1 server automatically consumes any remaining

On ARM64, in -dynlink mode (building a shared library or a plugin),
accessing global variable is made using the GOT. Currently, the
GOT accessing instruction sequence our assembler generates doesn't
handle large offset well, so we don't fold the offset into loads
and stores in the compiler. Currently, the rewrite rules are
guarded with the -shared flag. However, the GOT access
instructions are only generated in the -dynlink mode (which
implies -shared, but not the other direction).
CL 445535 attempted to remove the guard althgether. But that
causes build failure for -dynlink mode for the reason above. This
CL changes it to guard specifically on -dynlink mode, allowing
the optimization in more cases (-shared but not -dynlink build
modes).

In -pgo=auto mode, a package may be built multiple times. E.g. for
go build -pgo=auto cmd/a cmd/b
and both cmd/a and cmd/b imports package p, p may be built twice,
one using a's profile, one using b's. If we need to print p, e.g.
in "go list -deps" or when there is a build failure, p will be
printed twice, and currently we don't distinguish them.
We have a precedence for a similar case: for testing, there is the
original package, and the (internal) test version of the package
(which includes _test.go files). Packages that import the package
under testing may also have two versions (one imports the original,
one imports the testing version). In printing, the go command
distinguishes them by adding a "[p.test]" suffix for the latter,
as they are specifically built for the p.test binary.
We do the similar. When a package needs to be compiled multiple
times for different main packages, we attach the main package's
import path, like "p [cmd/a]" for package p built specifically
for cmd/a.

In -pgo=auto mode, the go command finds a profile named
default.pgo in the main package's directly, and if found, use it
as the profile for the build. Currently we only support a single
main package when -pgo=auto is used.
When multiple main packages are included in a build, they may
have different default profiles (or some have profiles whereas
some don't), so a common dependent package would need to be built
multiple times, with different profiles (or lack of). This CL
handles this. To do so, we need to split (unshare) the dependency
graph so they can attach different profiles.

Adds:
GOEXPERIMENT=loopvar (expected way of invoking)
-d=loopvar={-1,0,1,2,11,12} (for per-package control and/or logging)
-d=loopvarhash=... (for hash debugging)
loopvar=11,12 are for testing, benchmarking, and debugging.
If enabled,for loops of the form `for x,y := range thing`, if x and/or
y are addressed or captured by a closure, are transformed by renaming
x/y to a temporary and prepending an assignment to the body of the
loop x := tmp_x. This changes the loop semantics by making each
iteration's instance of x be distinct from the others (currently they
are all aliased, and when this matters, it is almost always a bug).
3-range with captured iteration variables are also transformed,
though it is a more complex transformation.
"Optimized" to do a simpler transformation for
3-clause for where the increment is empty.
(Prior optimization of address-taking under Return disabled, because
it was incorrect; returns can have loops for children. Restored in
a later CL.)
Includes support for -d=loopvarhash=<binary string> intended for use
with hash search and GOCOMPILEDEBUG=loopvarhash=<binary string>
(use `gossahash -e loopvarhash command-that-fails`).
Minor feature upgrades to hash-triggered features; clients can specify
that file-position hashes use only the most-inline position, and/or that
they use only the basenames of source files (not the full directory path).
Most-inlined is the right choice for debugging loop-iteration change
once the semantics are linked to the package across inlining; basename-only
makes it tractable to write tests (which, otherwise, depend on the full
pathname of the source file and thus vary).

For now this is simply a mechanical combination without any
relevant logic changes. This will make it easier to review
subsequent changes.

After CL 235820 all references to FD.rtimedout and FD.wtimedout
are guarded by mutexes. Therefore they can safely be changed
from type atomic.Bool to bool.

Go programs can now use the //go:wasmimport module_name function_name
directive to import functions from the WebAssembly runtime.
For now, the directive is restricted to the runtime and syscall/js
packages.

This simplifies the use of missingMethod and also opens the door to
further missingMethod-internal simplifications.

This CL allows missingMethod (and with it the assertableTo methods)
to provide an error cause without an extra external (and messy) call
of missingMethodCause. This latter function is now only called by
missingMethod and can be eliminated eventually in favor of more
precise error causes generated directly by missingMethod.
The change requires that missingMethod (and the assertableTo methods)
accept general types for both relevant argument types (rather than a
Type and a *Interface) so that error causes can report the appropriate
(possibly defined) type rather than the underlying interface type.

An inferred type argument must implement its type parameter's constraint's
methods whether or not a core type exists. This allows us to infer type
parameters used in method signatures.

This allows us to use missingMethod with different type comparers,
such as the global Identical predicate, or a unifier.
