[JSC] Make WasmIPInt's tierSupportsSIMD a runtime option (useWasmIPIntSIMD)
https://bugs.webkit.org/show_bug.cgi?id=298248
rdar://159681734
Reviewed by Daniel Liu and Yusuke Suzuki.
Add a feature flag, useWasmIPIntSIMD, to use while WASM IPInt SIMD
support is under development. Change WasmIPIntGenerator::tierSupportsSIMD
to be controlled by this runtime option. Other tier's tierSupportsSIMD
remain compile time constant.
Remove code with this pattern:
if (!Context::tierSupportsSIMD)
WASM_TRY_ADD_TO_CONTEXT(addCrash());
since WasmIPIntGenerator::addCrash() is a no-op and all other tier
have Context::tierSupportsSIMD == true, so this code has no effect.
This is probably a relic from the WasmLLInt handling of SIMD.
