This reverts commit 067bb443af.
Reason for revert:
Failing Darwin-arm builds because that testing environment does not access testdata
from sibling directories. A future change will likely be made to move this testdata
out of src/testdata to create a solution that doesn't require the single-file directory.

This text is used mainly for benchmark compression testing, and in one
net test. The text was prevoiusly in a src/testdata directory, but since
that directory would only include one file, the text is moved to the
existing src/compression/testdata directory.
This does not cause any change to the benchmark results.

Previously, cover printed directives (//go: comments) near the top of
the file unless they were in doc comments. However, directives
frequently apply to specific definitions, and they are not written in
doc comments to prevent godoc from printing them. Moving all
directives to the top of the file affected semantics of tests.
With this change, directives are kept together with the following
top-level declarations. Only directives that occur after all top-level
declarations are moved.

This CL does a few things.
1. It moves the existing "read a build ID" code out of the go command
and into cmd/internal/buildid.
2. It adds new code there to "write a build ID".
3. It adds better tests.
4. It encapsulates cmd/internal/buildid into a new standalone program
"go tool buildid".
The go command is going to use the new "write a build ID" functionality
in a future CL. Adding the separate "go tool buildid" gives "go build -x"
a printable command to explain what it is doing in that new step.
(This is similar to the go command printing "go tool pack" commands
equivalent to the actions it is taking, even though it's not invoking pack
directly.) Keeping go build -x honest means that other build systems can
potentially keep up with the go command.

Prior to this CL, flags such as NOSPLIT
on ATEXT Progs were stored in From3.Offset.
Some but not all of those flags were also
duplicated into From.Sym.Attribute.
This CL migrates all of those flags into
From.Sym.Attribute and stops creating a From3.
A side-effect of this is that printing an
ATEXT Prog can no longer simply dump From3.Offset.
That's kind of good, since the raw flag value
wasn't very informative anyway, but it did
necessitate a bunch of updates to the cmd/asm tests.
The reason I'm doing this work now is that
avoiding storing flags in both From.Sym and From3.Offset
simplifies some other changes to fix the data
race first described in CL 40254.
This CL almost passes toolstash-check -all.
The only changes are in cases where the assembler
has decided that a function's flags may be altered,
e.g. to make a function with no calls in it NOSPLIT.
Prior to this CL, that information was not printed.

cmd/link is clearly the way forward.
The original rationale for cmd/newlink was that it would be a clean Go reimplementation.
But when push came to shove, cmd/link got converted from C instead,
and all the work on build modes and the like is in cmd/link now.
Cleaning up cmd/link is likely a much better plan.
This directory is something to delete from releases and the
testdata is something that breaks every time the .6 format changes.
Fix both problems by just deleting it outright.
