Add FIPS symbol kinds that will be needed for FIPS support.
This is a separate CL to keep the re-generated changes in
the string methods separate from hand-written changes.
The separate symbol kinds will let us group the FIPS-related
code and data together, so that it can be checksummed at
startup, as required by FIPS.
It's also separate because it breaks buildall, by changing the
on-disk symbol kind enumeration. We want non-buildall
changes to be as simple as possible.

As the comment notes, all calls to Errorf now pass nil,
so remove that argument entirely.
There is a TODO to remove uses of Errorf entirely, but
that seems wrong: sometimes there is no symbol on
which to report the error, and in that situation, Errorf is
appropriate. So clarify that in the docs.

The old API was to do
r := obj.AddRel(sym)
r.Type = this
r.Off = that
etc
The new API is:
sym.AddRel(ctxt, obj.Reloc{Type: this: Off: that, etc})
This new API is more idiomatic and avoids ever having relocations
that are only partially constructed. Most importantly, it sets up
for sym.AddRel being able to check relocation validity in the future.
(Passing ctxt is for use in validity checking.)

Strictly speaking, the sort comparison was inconsistent
(and therefore invalid) for the sort-by-name case, if you had
a size 0
b size 1
c size 0
zerobase
That would result in the inconsistent comparison ordering:
a < b (by name)
b < c (by name)
c < zerobase (by zerobase rule)
zerobase < b (by zerobase rule)
This can't happen today because we only disable size-based
sort in a segment that has no zerobase symbol, but it's
confusing to reason through that, so clean up the code anyway.

For the SubFromLen64 codegen test case to work as intended, we need
to fold c-(-(x-d)) into x+(c-d).
Still, some instances of LeadingZeros are not optimized into single
CLZ instructions right now (actually, the LeadingZeros micro-benchmarks
are currently still compiled with redundant adds/subs of 64, due to
interference of loop optimizations before lowering), but perf numbers
indicate it's not that bad after all.

The TestProfilerStackDepth/heap test can spuriously fail if the profiler
happens to capture a stack with an allocation several frames deep into
runtime code. The pprof API hides runtime frames at the leaf-end of
stacks, but those frames still count against the profiler's stack depth
limit. The test checks only the first stack it finds with the desired
prefix and fails if it's not deep enough or doesn't have the right root
frame. So it can fail in that scenario, even though the implementation
isn't really broken.
Relax the test to check that there is at least one stack with desired
prefix, depth, and root frame.

If a variadic call to a variadic function has not enough/too many
arguments, then print the variadic argument in dotdotdot form
instead of as a slice type in the error message.

The original triple is `[13,17,5]` which don't existed in the Xorshift
RNG paper.
This CL use the right triple `[13,7,17]` for 64 bits RNG.

Add support for assembling the FMA instructions present in the LoongArch
base ISA v1.00. This requires adding a new instruction format and making
use of a third source operand, which is put in RestArgs[0].
The single-precision instructions have the `.s` prefix in their official
mnemonics, and similar Go asm instructions all have `S` prefix for the
other architectures having FMA support, but in this change they instead
have `F` prefix in Go asm because loong64 currently follows the mips
backends in the naming convention. This could be changed later because
FMA is fully expressible in pure Go, making it unlikely to have to hand-
write such assembly in the wild.
Example mapping between actual encoding and Go asm syntax:
fmadd.s fd, fj, fk, fa -> FMADDF fa, fk, fj, fd
(prog.From = fa, prog.Reg = fk, prog.RestArgs[0] = fj and prog.To = fd)
fmadd.s fd, fd, fk, fa -> FMADDF fa, fk, fd
(prog.From = fa, prog.Reg = fk and prog.To = fd)
This patch is a copy of CL 477716.
