Russ Cox e8eec3fbdb [dev.boringcrypto] cmd/compile: refine BoringCrypto kludge
Did not consider these fields being embedded or adopted
into structs defined in other packages, but that's possible too.
Refine the import path check to account for that.

Fixes 'go test -short golang.org/x/crypto/ssh' but also
adds a new test in internal/boring for the same problem.

Russ Cox 7b49445d0f [dev.boringcrypto] cmd/compile: hide new boring fields from reflection
This is terrible but much simpler, cleaner, and more effective
than all the alternatives I have come up with.

Lots of code assumes that reflect.DeepEqual is meaningful
on rsa.PublicKey etc, because previously they consisted only of
exported meaningful fields.

Worse, there exists code that assumes asn1.Marshal can be
passed an rsa.PublicKey, because that struct has historically
matched exactly the form that would be needed to produce
the official ASN.1 DER encoding of an RSA public key.

Instead of tracking down and fixing all of that code
(and probably more), we can limit the BoringCrypto-induced
damage by ensliting the compiler to hide the new field
from reflection. Then nothing can get at it and nothing can
be disrupted by it.

Kill two birds with one cannon ball.

I'm very sorry.

Russ Cox 991652dcf0 [dev.boringcrypto] cmd/link: work around DWARF symbol bug
The DWARF code is mishandling the case when the host object files
define multiple (distinct) symbols with the same name. They are mapped
to the same DWARF debug symbol, which then appears on the dwarfp
list multiple times, which then breaks the code that processes the list.
Detect duplicates and skip them, because that's trivial, instead of fixing
the underlying problem.

See #21566.

Ian Lance Taylor b63db76c4a testsanitizers: check that tsan program runs, skip tsan10 on gcc
Check not only that a tsan program can be built, but also that it runs.
This fails with some installations of GCC 7.

Skip the tsan10 program when using GCC, as it reportedly hangs.

This is a patch to help people build 1.9; we may be able to do a
better fix for 1.10.

Alberto Donizetti 193eda7291 time: skip ZoneAbbr test in timezones with no abbreviation
The testZoneAbbr assumes that

  Parse(RFC1123, t1.Format(RFC1123))

will always succeed. This is not true because Format will fall back to
the numeric zone (ex. -07) for timezones with no abbreviation, but
Parse won't accept the numeric zone when the layout specifies 'MST'
(an abbreviation).

Skip the zone abbreviation test in timezones with no abbreviation.

Cherry Zhang f20944de78 cmd/compile: set/unset base register for better assembly print
For address of an auto or arg, on all non-x86 architectures
the assembler backend encodes the actual SP offset in the
instruction but leaves the offset in Prog unchanged. When the
assembly is printed in compile -S, it shows an offset
relative to pseudo FP/SP with an actual hardware SP base
register (e.g. R13 on ARM). This is confusing. Unset the
base register if it is indeed SP, so the assembly output is
consistent. If the base register isn't SP, it should be an
error and the error output contains the actual base register.

For address loading instructions, the base register isn't set
in the compiler on non-x86 architectures. Set it. Normally it
is SP and will be unset in the change mentioned above for
printing. If it is not, it will be an error and the error
output contains the actual base register.

No change in generated binary, only printed assembly. Passes
"go build -a -toolexec 'toolstash -cmp' std cmd" on all
architectures.

Fixes #21064.
