Following comments on CL 76320. Breaks Cmd.Std{out,err} doc into three paragraphs and updates Cmd.Stdin formatting to match. Fixes an erroneous reference to Stdin in the output goroutine comment, while keeping the wording consistent between Stdin and Stdout/Stderr.

The response to a TXT lookup is a sequence of RRs, each of which contains a sequence of string fragments. The correct handling of the response is to do: for each rr { list = append(list, strings.Join(rr.fragments, "")) } (like in at dnsRR_TXT.Walk, used on most platforms). The Windows code incorrectly does: for each rr { list = append(list, rr.fragments...) } This CL fixes it to concatenate fragments, as it must. Fixes #21472.

If a Mac user has more than 256 groups, getGroupList returns -1 but does not correctly set n. We need to retry the syscall with an ever-increasing group size until we get all of the user's groups. The easiest way to test this change is to set n to a value lower than the current user's number of groups, test on a Mac and observe a failure, then apply the patch and test that it passes. Fixes #21067.

Currently, SetGCPercent(-1) disables GC, but doesn't wait for any currently running concurrent GC to finish, so GC can still be running when it returns. This is a change in behavior from Go 1.8, probably defies user expectations, and can break various runtime tests that depend on SetGCPercent(-1) to disable garbage collection in order to prevent preemption deadlocks. Fix this by making SetGCPercent(-1) block until any concurrently running GC cycle finishes. Fixes #22443.

The signature of the mapassign_fast* routines need to distinguish the pointerness of their key argument. If the affected routines suspend part way through, the object pointed to by the key might get garbage collected because the key is typed as a uint{32,64}. This is not a problem for mapaccess or mapdelete because the key in those situations do not live beyond the call involved. If the object referenced by the key is garbage collected prematurely, the code still works fine. Even if that object is subsequently reallocated, it can't be written to the map in time to affect the lookup/delete.

CL 76551 modified inline_callers.go to build everything, including the runtime, with -l=4. While that works in most places (and ideally should work everywhere), it blows out the nosplit stack on solaris/amd64. Fix this by only building the test itself with -l=4. This undoes some of the changes to this test from CL 73212, which originally changed the go tool to rebuild all packages with the given flags. This change modified the expected output of this test, so now that we can go back to building only the test itself with inlining, we revert these changes to the expected output. (That CL also changed log.Fatalf to log.Printf, but didn't add "\n" to the end of the lines, so this CL fixes that, too.) Fixes #22797.

Fixes VBLENDVP{D/S}, VPBLENDVB encoding for /is4 imm8[7:4] encoded register operand. Explanation: `reg[r]+regrex[r]+1` will yield correct values for 8..15 reg indexes, but for 0..7 it gives `index+1` results. There was no test that used lower 8 register with /is4 encoding, so the bug passed the tests. The proper solution is to get 4th bit from regrex with a proper shift: `reg[r]|(regrex[r]<<1)`. Instead of inlining `reg[r]|(regrex[r]<<1)` expr, using new `regIndex(r)` function. Test that reproduces this issue is added to amd64enc_extra.s test suite. Bug came from https://golang.org/cl/70650.

The sleep in question does not make sense if the stolen-from P cannot run the stolen G. The usleep(3) has been observed delaying execution of woken G's by ~60us; skipping it reduces the wakeup-to-execution latency to ~7us in these cases, improving CPU utilization.

The return values of the LoadLocation are inherently dependent on the runtime environment. Add LoadLocationFromTZData, whose results depend only on the timezone data provided as arguments.
