[SIMD] B3/OMG Support
https://bugs.webkit.org/show_bug.cgi?id=246347
Reviewed by Mark Lam.
Support B3/ the OMG tier for SIMD functions.
We add SimdValue and Const128Value as two new B3 value types, plus
opcodes for every wasm simd op.
We also add extra testing modes to simd spec tests to ensure that
the OMG tier is being fully exercised. This should be a temporary
measure until SIMD no longer requires tiering up from LLInt to BBQ.
Finally, we work around a bug in register allocation for SIMD functions
by disabling the use of ARM64 fp callee-saves.
