[JSC] Use VectorLoadXSplat in B3
https://bugs.webkit.org/show_bug.cgi?id=252120
rdar://105341630
Reviewed by Keith Miller.
This patch uses VectorLoadXSplat for VectorSplat(LoadX) pattern.
For SIMDLoadSplat wasm opcodes, we are emitting VectorSplat(LoadX) in B3.
But we were not successfully converting it to VectorLoadXSplat for Air.
This patch adds lowering for them so that we emit VectorLoadXSplat.
