[JSC] Wasm IPInt: always parse SIMD
https://bugs.webkit.org/show_bug.cgi?id=302402
rdar://164566289
Reviewed by Yusuke Suzuki and Keith Miller.
Now that SIMD is fully supported in IPInt, there's no need to avoid
parsing SIMD instructions/types when parsing for IPInt. We can
always just generate the metadata even if we won't be using it
if --useWasmIPIntSIMD=false is set (which sticks around only until
relaxed SIMD is complete). This is a better trade off since it removes
a conditional branch from SIMD paths when parsing.
And since we always parse SIMD, we can get rid of the
assertAboutStackSize hack.
I'll follow this up with a cleanup change to remove
Context::tierSupportsSIMD() since all tiers now have this hardcoded
to true.
Testing: Wasm stress tests with --testing build
