[ES6] Minimize ES6_CLASS_SYNTAX ifdefs
​https://bugs.webkit.org/show_bug.cgi?id=151006

Reviewed by Darin Adler.

This patch minimizes ENABLE_ES6_CLASS_SYNTAX ifdefs.
It keeps several ENABLE_ES6_CLASS_SYNTAX ifdefs in Parser.cpp.

• super meta property
• class declaration parsing
• class expression parsing
• class with import declaration

This change makes difference minimal between the enabled and disabled configurations;
reducing accidental build breaks of the disabled configuration.

• bytecompiler/BytecodeGenerator.h:

(JSC::BytecodeGenerator::constructorKind): Deleted.

• bytecompiler/NodesCodegen.cpp:
• parser/ASTBuilder.h:
• parser/NodeConstructors.h:
• parser/Nodes.h:
• parser/Parser.cpp:
• parser/Parser.h:

(JSC::Scope::hasDirectSuper): Deleted.
(JSC::Scope::needsSuperBinding): Deleted.

• parser/ParserFunctionInfo.h:
• parser/ParserTokens.h:
• parser/SyntaxChecker.h:
