This reverts commit 3027932ac3.
Reason for revert: It didn't work well enough; a replacement CL that skips external net tests altogether on iOS is coming.

The preallocated memory size is comparable to bytes.Buffer bootstraping
array length (bytes.Buffer was used before rewrite to strings.Builder).
Without preallocation, encodeWord does more than one allocation for
almost any possible input.
The regression happens because bytes.Buffer did a 80-bytes allocation
at the beginning of encodeWord while strings.Builder did several
smaller allocations (started with cap=0).

The iOS builder recently gained access to the GO_BUILDER_NAME
environment variable, which in turn enabled some net tests that
were previously guarded by testenv.Builder() == "". Some such tests
have been disabled because they don't work; others have increased
the pressure on open file descriptors, pushing the low iOS limit of
250.
Since many net tests run with t.Parallel(), the "too many open files"
error hit many different tests, so instead of playing whack-a-mole,
lower the file descriptor demand by skipping the most file
descriptor hungry test, TestTCPSpuriousConnSetupCompletionWithCancel.

Since subtests and subbenchmarks run in a separate goroutine, and thus
a separate stack, this entails capturing the stack trace at the point
tb.Run is called. The work of getting the file and line information from
this stack is only done when needed, however.
Continuing the search into the parent test also requires temporarily
holding its mutex. Since Run does not hold it while waiting for the
subtest to complete, there should be no risk of a deadlock due to this.

This was not a problem until now because the posets used by prove

are added to Pos (reducing maximum line number by 4x, to
1048575). They're added in cmd/internal/obj/<ARCH>.go

deal with them.
The linker currently does nothing with beginning-of-epilogue,

A new pass run after ssa building (before any other
optimization) identifies the "first" ssa node for each
statement. Other "noise" nodes are tagged as being never
appropriate for a statement boundary (e.g., VarKill, VarDef,
Phi).
Rewrite, deadcode, cse, and nilcheck are modified to move
the statement boundaries forward whenever possible if a
boundary-tagged ssa value is removed; never-boundary nodes
are ignored in this search (some operations involving
constants are also tagged as never-boundary and also ignored
because they are likely to be moved or removed during
optimization).
Code generation treats all nodes except those explicitly
marked as statement boundaries as "not statement" nodes,
and floats statement boundaries to the beginning of each
same-line run of instructions found within a basic block.
Line number html conversion was modified to make statement
boundary nodes a bit more obvious by prepending a "+".
The code in fuse.go that glued together the value slices
of two blocks produced a result that depended on the
former capacities (not lengths) of the two slices. This
causes differences in the 386 bootstrap, and also can
sometimes put values into an order that does a worse job
of preserving statement boundaries when values are removed.
Portions of two delve tests that had caught problems were
incorporated into ssa/debug_test.go. There are some
opportunities to do better with optimized code, but the
next-ing is not lying or overly jumpy.
Over 4 CLs, compilebench geomean measured binary size
increase of 3.5% and compile user time increase of 3.8%
(this is after optimization to reuse a sparse map instead
of creating multiple maps.)
This CL worsens the optimized-debugging experience with
Delve; we need to work with the delve team so that
they can use the is_stmt marks that we're emitting now.
The reference output changes from time to time depending
on other changes in the compiler, sometimes better,
sometimes worse.
This CL now includes a test ensuring that 99+% of the lines
in the Go command itself (a handy optimized binary) include
is_stmt markers.

The current Abs docs say:

The empty string is not an absolute path, so the docs suggest that the
empty string should be joined with the current working directory to
turn it into an absolute path. This was already the case on all
platforms other than Windows. Per the decision in issue #24441,
this change makes it work on Windows too.
Since the empty string is not a valid path for the purposes of calling
os.Stat on it, we can't simply add the empty string test case to
absTests, which TestAbs uses. It would error when trying to do:
info, err := os.Stat(path)
I didn't find a good way to modify TestAbs to handle this situation
without significantly complicating its code and compromising the test.
So, a separate test is created for testing Abs on empty string input.

Provide better statistics for the database pool. Add counters
for waiting on the pool and closes. Too much waiting or too many

Use 0-terminated opbyte sequences for Zlit-like movtabs instead of E=0xff.
movCodeFullPtr is unused (load full ptr is unsupported), but it should
be removed in a separate CL (if removed at all).
Passes toolstash-check.

On the API level this is just an update of the documentation to match
the current spec more closely.
On the implementation side, this is a rename of various unexported names.
For #22005.

Commit f8b4123613 (https://go-review.googlesource.com/35108) adjusted
the spec to uniformly use 'embedded' rather than 'anonymous' for struct
embedded fields. Adjust go/types' internal terminology.
Provide an additional accessor Var.IsEmbedded().
This is essentially a rename of an internal field and adjustments of
documentation.

The connRequest may return a nil conn value. However in a rare
case that is difficult to test for it was being passed to
DB.putConn without a nil check. This was an error as this
made no sense if the driverConn is nil. This also caused
a panic in putConn.
A test for this would be nice, but didn't find a sane
way to test for this condition.

A receiver type may have an (alias type) name and thus be 'named'
even though the name doesn't refer to a defined type. Adjust the

Even if we had an up-to-date package binary, we reran cgo anyway if
(1) we needed a header file for buildmode c-archive or c-shared, or
(2) we needed cgo-translated files source files for input to go vet.
Cache those outputs too, so that we can avoid cgo if possible.
Working toward exposing the cgo-generated files in go list.

To date, go run has required a list of .go files.
This CL allows in place of that list a single import path
or a directory name or a pattern matching a single patckage.
This allows 'go run pkg' or 'go run dir', most importantly 'go run .'.
The discussion in #22726 gives more motivation.
The basic idea is that you can already run 'go test .'
but if you're developing a command it's pretty awkward
to iterate at the same speed. This lets you do that,
by using 'go run . [args]'.
Fixes#22726.
