[JSC] Add StringLocaleCompare DFG node
https://bugs.webkit.org/show_bug.cgi?id=246893
rdar://101447718
Reviewed by Justin Michaud.
JetStream2/cdjs is heavily calling String#localeCompare. Let's add DFG node for
that to handle the simple case in the most efficient way.
This patch adds DFG StringLocaleCompare node, and it handles default locale
compare case. It removes type checks for String and result is
typed as Int32. This patch offers another 10% improvement in JetStream2/cdjs.
