There is no correctness reason to zero out the w.bytes array in (w
*huffmanBitWriter).reset, since w.nbytes is correctly set to zero. The elements of
the bytes array are always written sequentially, with nbytes indicating how many
elements have been written, and are only read up to the current value of nybytes.
We have a pprof profile of a web server that compresses its request/responses, and
the zeroing in reset() is taking up 2.6% of the CPU time of the server (and could
be causing more slowdowns elsewhere due to its effects on the cache). This
overhead may be showing up especially because there are many request/responses
that are all fairly small.
I'm not sure if the zeroing of the bytes array was intended as extra protection of
data across reset uses in the same program, but no protection is needed as long as
the huffman_bit_writer code remains correct.

Mobile targets are not supported by misc-compile trybots, as tracked in
golang.org/issue/25963, and need to be filtered out. The buildall.bash
script was created in CL 9438, back when it was a single all-compile
builder, and it was easier to filter out mobile targets in the script
than to come up with a pattern that matches all non-mobile targets.
As of CL 254740, all mobile targets (Android and iOS) have unique GOOS
values. That makes it it easy to filter them out in x/build/dashboard.
This was done in CL 258057. As a result, it's now viable to simplify
this script and perform all misc-compile target selection in x/build,
rather than having it spread it across two places.
Also, as of CL 10750, the all-compile builder has turned into multiple
misc-compile builders, so update the script description accordingly.

ARM64 used to require that all assembly frame sizes were of the form
16*N+8 because ARM64 requires 16-byte SP alignment and the assembler
added an 8 byte LR slot. This made all of the runtime.call* frame
sizes wonky. The assembler now rounds up the frame size appropriately
after adding any additional slots it needs, so this is no longer
necessary.
This CL cleans up the frame sizes of these functions so they look the
way you'd expect and match all other architectures.

Currently, runtime.call16 is defined and used only on 32-bit
architectures, while 64-bit architectures all start at call32 and go
up from there. This led to unnecessary complexity because call16's
prototype needed to be in a different file, separate from all of the
other call* prototypes, which in turn led to it getting out of sync
with the other call* prototypes. This CL adds call16 on 64-bit
architectures, bringing them all into sync, and moves the call16
prototype to live with the others.
Prior to CL 31655 (in 2016), call16 couldn't be implemented on 64-bit
architectures because it needed at least four words of argument space
to invoke "callwritebarrier" after copying back the results. CL 31655
changed the way call* invoked the write barrier in preparation for the
hybrid barrier; since the hybrid barrier had to be invoked prior to
copying back results, it needed a different solution that didn't reuse
call*'s stack space. At this point, call16 was no longer a problem on
64-bit, but we never added it. Until now.

The signature of call16 is currently missing the "typ" parameter. This
CL fixes this. This wasn't caught by vet because call16 is defined by
macro expansion (see #17544), and we didn't notice the mismatch with
the other call* functions because call16 is defined only on 32-bit
architectures and lives alone in stubs32.go.
Unfortunately, this means its GC signature is also wrong: the "arg"
parameter is treated as a scalar rather than a pointer, so GC won't
trace it and stack copying won't adjust it. This turns out to matter
in exactly one case right now: on 32-bit architectures (which are the
only architectures where call16 is defined), a stack-allocated defer
of a function with a 16-byte or smaller argument frame including a
non-empty result area can corrupt memory if the deferred function
grows the stack and is invoked during a panic. Whew. All other current
uses of reflectcall pass a heap-allocated "arg" frame (which happens
to be reachable from other stack roots, so tracing isn't a problem).
Curiously, in 2016, the signatures of all call* functions were wrong
in exactly this way. CL 31654 fixed all of them in stubs.go, but
missed the one in stubs32.go.

Previously by default, we extracted modules to a temporary directory,
then renamed it into place. This failed with ERROR_ACCESS_DENIED on
Windows if another process (usually an anti-virus scanner) opened
files in the temporary directory.
Since Go 1.15, users have been able to set
GODEBUG=modcacheunzipinplace=1 to opt into new behavior: we extract
modules at their final location, and we create and later delete a
.partial file to prevent the directory from being used if we crash.
.partial files are recognized by Go 1.14.2 and later.
With this change, the new behavior is the only behavior.
modcacheunzipinplace is no longer recognized.
Fixes#36568
