When a 8x16 shuffle matches a 32x4 shuffle (every group of 4 indices are
consecutive), and the first 2 indices are in the range [0-3], and the
other 2 indices are in the range [4-7], then we can match it to a
shufps. E.g. [0,2,4,6], [1,3,5,7]. These shuffles are commonly used to
extract odd/even floats.

Code like:
x = wasm_v32x4_shuffle(x, x, 1, 2, 3, 0);
is currently matched by S8x16Concat, which lowers to two instructions:
movapd xmm_dst, xmm_src
palignr xmm_dst, xmm_src, 0x4
There is a special case after a S8x16Concat is matched:.
- is_swizzle, the inputs are the same
- it is a 32x4 shuffle (offset % 4 == 0)
Which can have a better codegen:
- (dst == src) shufps dst, src, 0b00111001
- (dst != src) pshufd dst, src, 0b00111001
Add a new simd shuffle matcher which will match 32x4 rotate, and
construct the appropriate indices referring to the 32x4 elements.
pshufd for the given example. However, this matching happens after
S8x16Concat, so we get the palignr first. We could move the pattern
matching cases around, but it will lead to some cases where
where it would have matched a S8x16Concat, but now matches a
S32x4shuffle instead, leading to worse codegen.
Note: we also pattern match on 32x4Swizzle, which correctly generates

The signed and unsigned opcodes for vpaddl are separate enums, because

considered changing the signature, but none of the other instructions
use a NeonDataType, so it seems unnecessary.

There were some +/- infs hidden in that list of NaNs (and those were
repeated too). Add a NaN with top bit of payload unset. This will help
catch cases where we did not canonicalize results properly.

Now that 86 has branched, we can move bitmask into the SIMD MVP, it will
not affect the current OT. (We want any OT extension to include
bitmask.)
Bitmask was accepted into the proposal in
https://github.com/WebAssembly/simd/pull/201.

Load extends always load 8 bytes, so the access size does not depend on
MachineType of the load. The MachineType is used for classifying the
lane shape of the 8-byte load.
Also add cctest to load splats and load extends to test OOB. (Note that
load splats access size depends on MachineType).
Add regression test from clusterfuzz, minimized by ahaas@. Remove the
`--no-wasm-trap-handler` flag since we have a no_wasm_traps variant that
should test this flag.

The interpreter is not an execution tier in production any more. It's
only used in tests.
Thus, remove {ExecutionTier::kInterpreter} and instead add a
{TestExecutionTier} that still has {kInterpreter}.
If needed (in {TestingModuleBuilder::execution_tier()}), we translate
back from {TestExecutionTier} to {ExecutionTier} (for {kLiftoff} and
{kTurboFan} only).
The {TraceMemoryOperation} method, which is shared between interpreter
and production code, now receives a {base::Optional<ExecutionTier>}, and
we will just pass en empty optional if called from the interpreter.

This was previously running on TurboFan and scalar lowering. Since
Liftoff has gained support for shuffle instructions, we can run it
there too.

The load splat, load extend, load zero macros are essentially the same,
consolidate them into a single macro.
