For mips32 currently, we are using FP32, while the gcc may be FPXX,
which may generate .MIPS.abiflags and .gnu.attributes section with
value as FPXX. So the kernel will treat the exe as FPXX, and may
choose to use FR=1 FPU mode for it.
Currently, in Go, we use 2 lwc1 to load both half of a double value
to a pair of even-odd FPR. This behavior can only work with FR=0 mode.
In FR=1 mode, all of 32 FPR are 64bit. If we lwc1 the high-half of a double
value to an odd FPR, and try to use the previous even FPR to compute, the
real high-half of even FPR will be unpredicatable.
We set -mfp32 to force the gcc generate FP32 code and section value.
More details about FP32/FPXX/FP64 are explained in:
https://web.archive.org/web/20180828210612/https://dmz-portal.mips.com/wiki/MIPS_O32_ABI_-_FR0_and_FR1_Interlinking
When GOMIPS/GOMIPS64 is set as softfloat, we should also pass
-msoft-float to gcc.
Here we also add -mno-odd-spreg option, since Loongson's CPU cannot use
odd-number FR in FR=0 mode.

This test contained a data race.
On line 437, db.BeginTx starts a goroutine that runs tx.awaitDone,
which reads tx.keepConnOnRollback.
On line 445, the test writes to tx.keepConnOnRollback.
tx.awaitDone waits on ctx, but because ctx is timeout-based,
there's no ordering guarantee between the write and the read.
The race detector never caught this before
because the context package implementation of Done
contained enough synchronization to make it safe.
That synchronization is not package of the context API or guarantees,
and the first several releases it was not present.
Another commit soon will remove that synchronization,
exposing the latent data race.
To fix the race, emulate a time-based context
using an explicit cancellation-based context.
This gives us enough control to avoid the race.

MOV*nop and MOV*reg seem superfluous. They are there to keep type
information around that would otherwise get thrown away. Not sure
what we need it for. I think our compiler needs a normalization of
how types are represented in SSA, especially after lowering.
MOV*nop gets in the way of some optimization rules firing, like for
load combining.
For now, just fold MOV*nop and MOV*const. It's certainly safe to
do that, as the type info on the MOV*const isn't ever useful.

As done with other equality tests, zero extend before subtraction rather than
after (or in this case, at the same time). While at face value this appears to
require more instructions, in reality it allows for most sign extensions to
be completely eliminated due to correctly typed loads. Existing optimisations
(such as subtraction of zero) then become more effective.
This removes more than 10,000 instructions from the Go binary and in particular,
a writeBarrier check only requires three instructions (AUIPC, LWU, BNEZ) instead
of the current four (AUIPC, LWU, NEGW, BNEZ).

Based on golang/go#39464 (https://go-review.googlesource.com/c/go/+/237057) from
Aaron Bieber <deftly@gmail.com>, however the race_openbsd_amd64.syso file has
been built on OpenBSD 6.4 and necessary changes added to race.bash.

Check that the target of a constant load is a register and add test coverage
for this error condition. While here, rename the RISC-V testdata and tests
to be consistent with other platforms.

For assertE2I and assertI2I, there's no need to pass through the

For assertE2I2 and assertI2I2, there's no need for an extra bool
result parameter: it's redundant with testing the returned interface
value for nil.

Previous CL did remove selectnbrecv2 in runtime, the compiler now only
call selectnbrecv, so remove this. Make this as separated CL because it
adds much of noise to git stat.
