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.

Patch by Michael Saboff <msab...@apple.com> on 2011-11-08

+        Fix PropertyAccessRecords in DFG JIT to take account of branch compaction.

+
+        Reviewed by Filip Pizlo.
+
+        The DFG JIT presently calculates a set of offsets early, before branches have been compacted.
+        This won't work on ARMv7.
