[JSC] WASM IPInt SIMD: do not try to access jsCallingConvention() when
signature has v128
https://bugs.webkit.org/show_bug.cgi?id=300518
rdar://162383774
Reviewed by Yusuke Suzuki.
We should check for v128 in the signature before accessing jsCallingConvention()
since imports aren't allowed to have v128 (and JSCallingConvention
RELEASE_ASSERTs that).
Testing: found by v8/simd-errors.js when running JIT-less Wasm SIMD
