4aa4d6e21a [codeview] Add support for new type records.
This adds support for parsing and dumping the following
symbol types:

S_LPROCREF
S_ENVBLOCK
S_COMPILE2
S_REGISTER
S_COFFGROUP
S_SECTION
S_THUNK32
S_TRAMPOLINE

As of this patch, the test PDB files no longer have any unknown
symbol types.

13dc004006 [codeview] Refactor symbol records to use same pattern as types.
This will pave the way to introduce a full fledged symbol visitor
similar to how we have a type visitor, thus allowing the same
dumping code to be used in llvm-readobj and llvm-pdbdump.

d4ae961cf6 [codeview] Some cleanup of Symbol Records.
* Reworks the CVSymbolTypes.def to work similarly to TypeRecords.def.
* Moves some enums from SymbolRecords.h to CodeView.h to maintain
  consistency with how we do type records.
* Generalize a few simple things like the record prefix
* Define the leaf enum and the kind enum similar to how we do with tyep
  records.

26fcd8455c Make CodeView record serialization more generic.
This introduces a variadic template and some helper macros to
safely and correctly deserialize many types of common record
fields while maintaining error checking.
