We bailed out while printing codeview for an MSVC compiled
SemaExprCXX.cpp that used this record. The MS reference headers look
incorrect here, which is probably why we had this bug. They use a 32-bit
enum as the field type, but the actual record appears to use one byte
for the cookie kind followed by a flags byte.

This converts remaining uses of ByteStream, which was still
left in the symbol stream and type stream, to using the new
StreamInterface zero-copy classes.
RecordIterator is finally deleted, so this is the only way left
now. Additionally, more error checking is added when iterating
the various streams.
With this, the transition to zero copy pdb access is complete.

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.

This reverts commit r271024 due to error: static_assert failed
"You must either provide a specialization of VarStreamArrayExtractor
or a custom extractor"
llvm-svn: 271026
This reduces the amount of memory used by llvm-pdbdump by roughly
1/3 of the size of the PDB file.

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.
llvm-svn: 270628
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.
