[JSC] Use wasm SIMD optimizations in x64 too
rdar://172715980
https://bugs.webkit.org/show_bug.cgi?id=310072
Reviewed by Justin Michaud.
Add x64 AVX SIMD shuffle specializations. We unlock some of ARM64 SIMD
optimizations for x64 when the pattern is supported in AVX.
Tests: Source/JavaScriptCore/b3/testb3_1.cpp
Source/JavaScriptCore/b3/testb3_7.cpp
