[JSC] Add constant materialization JIT code for x64
https://bugs.webkit.org/show_bug.cgi?id=305532
rdar://168193277
Reviewed by Sosuke Suzuki.
This patch adds more wide variety of constants for
move128ToVector / move64ToDouble / move32ToFloat in x64. This is a
preparation for SIMD optimization in x64 in YarrJIT where it needs these
constant materializations for masks.
