Log Message:
-----------
[SIMD] SIMD functions should support Linear Scan and Graph Colouring register
allocators.
https://bugs.webkit.org/show_bug.cgi?id=246348
Reviewed by Yusuke Suzuki.
Today, we disable the linear scan and graph coloring register allocators
when WASM SIMD is enabled. Let's fix that by making them conservatively
treat floats as 128 bits when SIMD is enabled.
