Simplify / optimize JSC's LiteralParser: - Avoid storing the start/end pointers inside LiteralParserToken, as they are not actually needed. We already have a `stringStart + length` for strings/identifiers, which is all that's needed. - Stop using LiteralParserToken::stringIs8Bit for identifiers. Unlike strings, identifiers always use the same character type as the LiteralParser. This also avoids some unnecessary branching.
