WebKit spends 5% of total time parsing WorldCup.svg in bad parsing code

These two (misdesigned) lines in SVGPathParser::parseSVG() account for over 5%
of total time:
d = d.replace(',', ' ');
d = d.simplifyWhiteSpace();

No need to do either.  Just encoding that logic into the parser and do a single
walk over the string would be much faster.

Somewhere there is a darin thinking "i told you so..." ;)
