* Code refine and adding missing features
1. Add new level for built in symbols.
2. Fix issues for structure members' qualifiers.
3. Global qualifier fix.
4. IO Mapper refine. Add support for checking with mangle names.
* Additional missing features
* Invariant member. (Only check non-interface).
* Split block nesting level and struct nesting level. To fix issues of checking 'invariant' qualifier.
Current grammar would check block/struct member without its parent class's information.
So we split nesting level, and 'invariant' would only be checked within a struct.
* Format anonymous block names. Refine codes for symbols from all kinds of resouces.
* Fix writeonly check.
* Use LValueBase to find operator.
* Fix random null ptr issue.
* invariant check, stage in io mapping, reference parameter should be used and remove wrong codes introduced with ordering vector.
* Remained: to be fixed with double check link.vk.multiblocksValid
* Fix version error.
invariant
* Revert loc modification.
Note: This affects any downstream consumers of glslang's traverser. Let me know if there are any issues. Essentially, you will need to change the functions that were pointed to into overriding base-class members instead. See the examples in this check in.

For 4.2, largely, it is only the grammar that is working. Productions and semantics are mostly missing. Lexical analysis is mostly done, but not in the preprocessor, which still can't handle uint and double literals.
The grammar and token names are reorganized to match the specification, to allow easier comparison between the specification and the working grammar.
