Created an attachment (id=47345)
 --> (https://bugs.webkit.org/attachment.cgi?id=47345)
A new JavaScript Grammar, which passes all jscore regression tests.

Compared to the bison parser on SunSpider parser tests, namely jquery,
mootools, prototype. The AST is the same. There are some divot differences
because regular expression literals are not correctly handled by the bison
parser. Line infos for non-statements are useless for bison parser.
