(JSC::jsStrDecimalLiteral):

• runtime/LiteralParser.cpp: Ditto.

(JSC::::Lexer::lexNumber):

• wtf/dtoa.cpp: Replaced old strtod with a new version that uses the new StringToDoubleConverter.

It takes a template argument to allow clients to determine statically whether it should allow
junk after the numbers or not.
