[JSC] WASM IPInt SIMD: support v128 in IPInt to BBQ loop OSR
https://bugs.webkit.org/show_bug.cgi?id=299831
rdar://161608423
Reviewed by Yusuke Suzuki and Daniel Liu.
Follow the existing BBQ to OMG loop OSR scratch buffer usage pattern,
which is that for functions that use SIMD, allocate two scratch
buffer "slots" (slot is uint64) per item so that v128 sized
values can fit.
Tested by running stress/{simd-osr.js, simd-osr-many-vectors.js}
tests with --useWasmIPIntSIMD=true and see that they now pass.
