[JSC] RegExp.test inline is missing some stack overflow checks
https://bugs.webkit.org/show_bug.cgi?id=250873
rdar://104072550
Reviewed by Yusuke Suzuki.
The RegExp.test inline code is missing two stack overflow checks.
1) When compiling the pattern string to a YarrPattern, we checked for stack overflow,
but didn't do anything with the failure.
2) When allocating the stack space needed to execute the JIT code for the expression
we need to first check that we have enough stack.
This change adds checks for both cases using the JSRegExpResult::JITCodeFailure return value when we
would have overflowed the stack. The results checking code after the inline code sees that error
value, it will now call out to the appropriate C++ helper function to perform the match.
Those functions are capable of throwing Out of Stack exceptions.
