Towards 8 Bit Strings: Templatize JSC::Parser class by Lexer type
​https://bugs.webkit.org/show_bug.cgi?id=71761

Templatized Parser based on Lexer<T>. Moved two enums,
SourceElementsMode and FunctionRequirements out of Parser definition
to work around a clang compiler defect.

Cleaned up SourceCode data() to return StringImpl* and eliminated
the recently added stringData() virtual method.

To keep code in Parser.cpp and keep Parser.h small, the two flavors
of Parser are explicitly instantiated at the end of Parser.cpp.
