The rules for go:notinheap were recently tweaked to disallow stack
allocation (CL 249917). This CL updates the documentation about
go:notinheap in runtime/HACKING.md.

We grow the backing store on append by 2x for small sizes and 1.25x
for large sizes. The threshold we use for picking the growth factor
used to depend on the old length, not the old capacity. That's kind of
unfortunate, because then doing append(s, 0, 0) and append(append(s,
0), 0) do different things. (If s has one more spot available, then
the former expression chooses its growth based on len(s) and the
latter on len(s)+1.) If we instead use the old capacity, we get more
consistent behavior. (Both expressions use len(s)+1 == cap(s) to
decide.)

The CL 249758 added `FMOVQ $vcon, Vd` instruction and assembler used
128-bit simd literal-loading to load `$vcon` from pool into 128-bit vector
register `Vd`. Because Go does not have 128-bit integers for now, the
assembler will report an error of `immediate out of range` when
assembleing `FMOVQ $0x123456789abcdef0123456789abcdef, V0` instruction.
This patch lets 128-bit integers take two 64-bit operands, for the high
and low parts separately and adds `VMOVQ $hi, $lo, Vd` instruction to
move `$hi<<64+$lo' into 128-bit register `Vd`.
In addition, this patch renames `FMOVQ/FMOVD/FMOVS` ops to 'VMOVQ/VMOVD/VMOVS'
and uses them to move 128-bit, 64-bit and 32-bit constants into vector
registers, respectively
Update the go doc.

The 387 port needs to load a floating-point control word from a
global location to implement float32 arithmetic.
When compiling with -pie, loading that control word clobbers an
integer register. If that register had something important in it, boom.
Fix by using LEAL to materialize the address of the global location
first. LEAL with -pie works because the destination register is
used as the scratch register.
387 support is about to go away (#40255), so this will need to be
backported to have any effect.
No test. I have one, but it requires building with -pie, which
requires cgo. Our testing infrastructure doesn't make that easy.
Not worth it for a port which is about to vanish.

Other test flags passed to the test binary, such as -run or -count, are
equally pointless when -c or -i are used, since the test binary is never
run. However, custom flags in that scenario are far more likely to be
due to human error, such as:
# note the "ldflags" typo, which silently did nothing
go test -c -lflags=-w
Instead, make this scenario error. It seems unlikely that anyone is
using -c along with intended custom-defined test flags, and if they are,
removing those extra flags that do nothing is probably a good idea
anyway.
We don't add this restriction for the flags defined in 'go help
testflag', since they are far less likely to be typos or unintended
mistakes. Another reason not to do that change is that other commands
similarly silently ignore no-op flags, such as:
# -d disables the build, so -ldflags is never used
go get -d -ldflags=-w

The IndexString implementation in the bytealg package requires that
the string passed into it be in the range '2 <= len(s) <= MaxLen'
where MaxLen may be any value (including 0).
CL 156998 added calls to bytealg.IndexString where MaxLen was not
first checked. This led to an illegal instruction on s390x with
the vector facility disabled.
This CL guards the calls to bytealg.IndexString with a MaxLen check.
If the check fails then the code now falls back to the pre CL 156998
implementation (a loop over the runes in the string).
Since the MaxLen check is now in place the generic implementation is
no longer called so I have returned it to its original unimplemented
state.
In future we may want to drop MaxLen to prevent this kind of
confusion.

The modload.LoadTests global variable is subsumed by a field in the

Some functions are protected by locks that are not directly accessible

The Go 1.16 development cycle has started. This is the time to update
all golang.org/x/... module versions that contribute packages to the
std and cmd modules in the standard library to latest master versions.
Those versions have already gone through code review, and now they
will undergo additional testing during the development period.
If there are new issues in these dependencies discovered, we have
development period to deal with that. We will do this update once
more at the end of the development cycle, by the code freeze, and
so doing it now will make that update smaller and safer.
Overall, this change will help us build confidence that the
Go 1.16 release and its selected dependencies will be robust.
Also increment the Go language version to 1.16 in standard library
go.mod files.

For a common pattern of iterating only over top-level compilation units (CU)
Reader.SkipChildren has decode and meterialize all CU subentries just
to skip them, because DW_TAG_compile_unit does not have DW_AT_sibling.
However, CUs have total size encoded before the unit and we already parse them
and know all unit sizes.
Optimize Reader.SkipChildren to use that size when skipping CUs children.
This speeds up iteration over a 1.3GB object file from 7.5s to 0.73s.
