Bug 1631228 - wasm ion simd, part 2: MacroAssembler and other infrastructure. r=bbouvier
(deleted), text/x-phabricator-request
Details

Add Ion support for wasm SIMD for x64, SSE4.1 or better, non-AVX. A lot of the code will simply be ported from the old SIMD.js code. A lot of the rest will just use the new masm interfaces introduced in bug 1478632.

Remove the MIRTypes for SIMD.js and instead add a single new type,
MIRType::Simd128, which is int/float and lane-width agnostic.

Remove various things that referenced the old types but were only
useful for SIMD.js and should have been removed before.
