Thomas Lively 27748363da [WebAssembly] Enable recently implemented SIMD operations
Summary:
Moves a batch of instructions from unimplemented-simd128 to simd128
because they have recently become available in V8.

Sanjay Patel 85a2146c15 [SDAG] fold insert_vector_elt with undef index
Similar to:
rG4c47617627fb

This makes the DAG behavior consistent with IR's insertelement.

https://bugs.llvm.org/show_bug.cgi?id=42689

I've tried to maintain test intent for AArch64 and WebAssembly
by replacing undef index operands with something else.

Sanjay Patel 4c47617627 [SDAG] fold extract_vector_elt with undef index
This makes the DAG behavior consistent with IR's extractelement after:
rGb32e4664a715

https://bugs.llvm.org/show_bug.cgi?id=42689

I've tried to maintain test intent for WebAssembly.
The AMDGPU test is trying to test for crashing or other bad behavior,
but I'm not sure if that's possible after this change.

Thomas Lively 64a39a1c4e [WebAssembly] Add unimplemented-simd128 subtarget feature
Summary:
This is a third attempt, but this time we have vetted it on Windows
first. The previous errors were due to an uninitialized class member.

Thomas Lively eb6f9abd41 [WebAssembly] Add simd128-unimplemented subtarget feature
This is a second attempt at r350778, which was reverted in
r350789. The only change is that the unimplemented-simd128 feature has
been renamed simd128-unimplemented, since naming it
unimplemented-simd128 somehow made the simd128 feature flag enable the
unimplemented-simd128 feature on Windows.

Thomas Lively 2eeade1814 [WebAssembly] Add unimplemented-simd128 subtarget feature
Summary:
This replaces the old ad-hoc -wasm-enable-unimplemented-simd
flag. Also makes the new unimplemented-simd128 feature imply the
simd128 feature.

Summary:
Gates v128.const, f32x4.sqrt, f32x4.div, i8x16.extract_lane_u, and
i16x8.extract_lane_u on the --wasm-enable-unimplemented-simd flag,

Wouter van Oortmerssen 49482f824a [WebAssembly] replaced .param/.result by .functype
Summary:
This makes it easier/cleaner to generate a single signature from
this directive. Also:
- Adds the symbol name, such that we don't depend on the location
  of this directive anymore.
- Actually constructs the signature in the assembler, and make the
  assembler own it.
- Refactor the use of MVT vs ValType in the streamer and assembler
  to require less conversions overall.
- Changed 700 or so tests to use it.

Thomas Lively 11a332d08d [WebAssembly] Handle undefined lane indices in SIMD patterns
Summary:
Undefined indices in shuffles can be used when not all lanes of the
output vector will be used. This happens for example in the expansion
of vector reduce operations. Regardless, undefs are legal as lane
indices in IR and should be supported.

Summary:
This change makes the tests more focused and avoids problematic
interactions between the testing modes and instruction encoding. This
change also allows the other tests to use less verbose output and
stricter checks.

Thomas Lively a0d25815a0 [WebAssembly] v8x16.shuffle
Summary:
Since the shuffle mask is not exposed as an operand in the native ISel
DAG, create a new WebAssembly ISD node exposing the mask. The mask is
lowered as sixteen immediate byte indices no matter what type the
original vector shuffle was operating on.

Wouter van Oortmerssen 8a9cb242fb [WebAssembly] Added default stack-only instruction mode for MC.
Summary:
Made it convert from register to stack based instructions, and removed the registers.
Fixes to related code that was expecting register based instructions.
Added the correct testing flag to all tests, depending on what the
format they were expecting so far.
Translated one test to stack format as example: reg-stackify-stack.ll

tested:
llvm-lit -v `find test -name WebAssembly`

Thomas Lively 2ee686da27 [WebAssembly] Arbitrary BUILD_VECTOR and remove i64x2.mul
Summary:
This CL adds support for arbitrary BUILD_VECTORS, i.e. not splats and
not consts. This is the last feature needed to properly lower v2i64
multiplies without a i64x2.mul instruction (which is not in the spec),
so i64x2.mul is removed as well.
