[JSC] Scan string literal with SIMD
https://bugs.webkit.org/show_bug.cgi?id=296917
rdar://157537935
Reviewed by Keith Miller.
This patch introduces SIMD scanning for JS lexer's string literal
parsing. String literal tends to be longer than any other things in
general, and scanning it quickly via SIMD is effective.
