ce3ee7cdae cmd/internal/obj: stop storing Text flags in From3
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.

Sample before:

"".Ctz64 t=1 size=63 args=0x10 locals=0x0
	0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35)	TEXT	"".Ctz64(SB), $0-16
	0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35)	FUNCDATA	$0, gclocals·f207267fbf96a0178e8758c6e3e0ce28(SB)

Sample after:

"".Ctz64 t=1 nosplit size=63 args=0x10 locals=0x0
	0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35)	TEXT	"".Ctz64(SB), NOSPLIT, $0-16
	0x0000 00000 (/Users/josh/go/tip/src/runtime/internal/sys/intrinsics.go:35)	FUNCDATA	$0, gclocals·f207267fbf96a0178e8758c6e3e0ce28(SB)

Observe the additional "nosplit" in the first line
and the additional "NOSPLIT" in the second line.

53984e5be2 compress/flate: optimize huffman bit encoder
Part 1 of optimizing the deflater. This optimizes the bitwriter by:

* Removing allocations.
* Storing compound values for bit codes instead of 2 separate tables.
* Accumulate 48 bits between writes instead of 24.
* Inline bit flushing.

This also contains code that will be used in later CL's
(writeBlockDynamic, writeBlockHuff).

Tests for Huffman bit writer encoding regressions has been added.

fb880b8a03 cmd/newlink: delete
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.

was introduced in https://codereview.chromium.org/537543003.

Accepting this will remove the support for older version of
sel_ldr. I've confirmed that both pepper_40 and current
pepper_canary have this syscall.

After this change, we need sel_ldr from pepper_39 or above to
work.

44ab8d95d3 undo CL 176900044 / 561398621ba7
Turns out it *is* needed because the cmd/link tests expect to find their own files.

««« original CL description
misc/nacl: exclude cmd/link from the test zip.

It does not appear to be necessary, and cmd/link does not appear in release branches.

0c2a727477 build: make nacl pass
Add nacl.bash, the NaCl version of all.bash.
It's a separate script because it builds a variant of package syscall
with a large zip file embedded in it, containing all the input files
needed for tests.

Disable various tests new since the last round, mostly the ones using os/exec.

Fixes #7945.
