Zachary Turner 1de49c9ffd Resubmit "[pdb] Allow zero-copy read support for symbol streams.""
Due to differences in template instantiation rules, it is not
portable to static_assert(false) inside of an invalid specialization
of a template.  Instead I just =delete the method so that it can't
be used, and leave a comment that it must be explicitly specialized.

Chad Rosier 6c247c8cc8 Revert "[pdb] Allow zero-copy read support for symbol streams."
This reverts commit r271024 due to error: static_assert failed
"You must either provide a specialization of VarStreamArrayExtractor
or a custom extractor"

Zachary Turner 3a9a23ae62 [pdb] Allow zero-copy read support for symbol streams.
This reduces the amount of memory used by llvm-pdbdump by roughly
1/3 of the size of the PDB file.

Zachary Turner 4caa1bf0bd [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.

Zachary Turner cac29ae038 Dump symbol record details in llvm-pdbdump
This makes use of the newly introduced `CVSymbolVisitor` to dump details
of each type of symbol record in the symbol streams.  Future patches will
bring this visitor based dumping to the publics stream, as well as
creating a `SymbolDumpDelegate` to print more information about
relocations etc.
