[JSC] Wasm: remove special case SIMD entrypoint and tier up mechanism
https://bugs.webkit.org/show_bug.cgi?id=301122
rdar://163062083
Reviewed by Yusuke Suzuki.
Now that the usual IPInt entry point preserves vector registers,
let's remove the special-case tier-up-directly-to-BBQ-for-SIMD
entry point, and instead use the same mechanism used when
!Options::useWasmIPInt(), which is that the tier up counter is set to 0
and the prologue OSR path will synchronously compile and jump to the
JIT replacement.
Until relaxed SIMD is completed (or at least IPInt is at parity with
BBQ/OMG), we still need to keep the !Options::useWasmIPIntSIMD() case
working (so that the existing relaxed SIMD tests can be run), but
let's remove some of the complexity by combining these cases.
Testing: the relaxed SIMD tests exercise this case.
Additionally, I ran the Wasm tests with --useWasmIPIntSIMD=false
