This was originally reverted because of some non-deterministic
failures on certain buildbots. Luckily ASAN eventually caught
this as a stack-use-after-scope, so the fix is included in
this patch.

This is causing failures on linux bots with an invalid stream
read. It doesn't repro in any configuration on Windows, so
reverting until I have a chance to investigate on Linux.

This allows us to use yaml2obj and obj2yaml to round-trip CodeView
symbol and type information without having to manually specify the bytes
of the section. This makes for much easier to maintain tests. See the
tests under lld/COFF in this patch for example. Before they just said
SectionData: <blob> whereas now we can use meaningful record
descriptions. Note that it still supports the SectionData yaml field,
which could be useful for initializing a section to invalid bytes for
testing, for example.

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.

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.

Previously we would expect certain subsections to appear
in a certain order because some subsections would reference
other subsections, but in practice we need to support
arbitrary orderings since some object file and PDB file
producers generate them this way. This also paves the
way for supporting Yaml <-> Object File conversion of
CodeView, since Object Files typically have quite a
large number of subsections in their debug info.

This adds implementations for Symbols and FrameData, and renames
the existing codeview::StringTable class to conform to the
DebugSectionStringTable convention.
