      Add test case for F32x4Extract · e06c65ec
      Ng Zhi An authored 
      The test case SimdF32x4ExtractWithI32x4 was still passing when the codegen for
F32x4Extract was entirely commented out. This change adds a new test
cases that specifically exercises F32x4ExtractLane.

It copies what is done in SimdI32x4SplatFromExtract,
which involves moving the splatted and
extracted values around locals, to ensure we move the values around
registers and not unintentionally reuse registers that we splatted to,
without actually extracting anything.

Note that the existing SimdF32x4ExtractWithI32x4 is kept because it is
used to test scalar lowering passes.

      [wasm simd] Run no lowering tests for I64x2 and F64x2 · c84e19ea
      Ng Zhi An authored 
      Lowering does not work correctly for I64x2 and F64x2. Those tests are
guarded with X64, so it is fine, but if we remove the guard next
time, the failing tests will be confusing.

      [turbofan] Improve load poisoning tests. · 2048e5b7
      Artem Serov authored 
      Introduce a helper class for regular expression parsing
and use it to improve load poison tests readability and
maintainability.

Extend load poisoning tests for arm64 platform (e.g.
for both regular and compressed references cases).

      [wasm] Introduce WasmIndirectFunctionTable · 2fe2a08b
      Andreas Haas authored 
      This is the first of three CLs which refactors indirect function calls
through tables with index > 0 to work without runtime calls.

The first CL introduces the WasmIndirectFunctionTable heap object. For
a table of type anyfunc within a WebAssembly instance,
WasmIndirectFunctionTable stores the size, the signature id's, the
call targets, and the reference parameters for that table. I used the
names that are already used for the matching fields of the
WasmInstanceObject.

The second CL expands the IndirectFunctionTableEntry to work also on
WasmIndirectFunctionTable objects. All changes to a function table go
through this class.

The third CL introduces uses of the WasmIndirectFunctionTable. In this
CL I change the code generation in TurboFan to replace runime calls with
direct accesses to the new WasmIndirectFunctionTable. Additionally I
extended the initialization of WasmIndirectFunctionTable, and also
implement Table.grow.
