<h3>Log Message</h3>
<pre>[JSC] add additional bit to JSTokenType bitfield
https://bugs.webkit.org/show_bug.cgi?id=165091
Patch by Caitlin Potter <caitp@igalia.com> on 2016-12-02
Reviewed by Geoffrey Garen.
JSTests:
* stress/bug-165091.js: Added.
(shouldThrowSyntaxError):
Source/JavaScriptCore:
Avoid overflow which causes keyword tokens to be treated as unary
tokens now that "async" is tokenized as a keyword, by granting an
additional 64 bits to be occupied by token IDs.
* parser/ParserTokens.h:</pre>
