[JSC] Implement RegExp SIMD path for x64 too
https://bugs.webkit.org/show_bug.cgi?id=306690
rdar://169336634
Reviewed by Keith Miller.
This patch implements RegExp SIMD fast path for x64 too. Mostly the same
to ARM64, but using ptest for testing instead of vectorSwizzle2 since it
does not exist in x64.
