3c82f40b07 [CodeView] Support remaining debug subsection types
This adds support for Symbols, StringTable, and FrameData subsection
types.  Even though these subsections rarely if ever appear in a PDB
file (they are usually in object files), there's no theoretical reason
why they *couldn't* appear in a PDB.  The real issue though is that in
order to add support for dumping and writing them (which will be useful
for object files), we need a way to test them.  And since there is no
support for reading and writing them to / from object files yet, making
PDB support them is the best way to both add support for the underlying
format and add support for tests at the same time.  Later, when we go
to add support for reading / writing them from object files, we'll need
only minimal changes in the underlying read/write code.

f54de04c6e [llvm-pdbdump] Support native ordering of subsections in raw mode.
This is the same change for the YAML Output style applied to the
raw output style.  Previously we would queue up all subsections
until every one had been read, and then output them in a pre-
determined order.  This was because some subsections need to be
read first in order to properly dump later subsections.  This
patch allows them to be dumped in the order they appear.

5d88e16362 [CodeView] Handle Cross Module Imports and Exports.
While it's not entirely clear why a compiler or linker might
put this information into an object or PDB file, one has been
spotted in the wild which was causing llvm-pdbdump to crash.

This patch adds support for reading-writing these sections.
Since I don't know how to get one of the native tools to
generate this kind of debug info, the only test here is one
in which we feed YAML into the tool to produce a PDB and
then spit out YAML from the resulting PDB and make sure that
it matches.

f028d10a98 [CodeView] Rename ModuleDebugFragment -> DebugSubsection.
This is more concise, and matches the terminology used in other
parts of the codebase more closely.
