2c2955a045 [codeview] Add support for label type records
MASM can produce these type records.

3c488ca5a4 [codeview] Use separate records for LF_SUBSTR_LIST and LF_ARGLIST
They are structurally the same, but now we need to distinguish them
because one record lives in the IPI stream and the other lives in TPI.

d9b4aa7542 [PDB] Make streams carry their own endianness.
Before the endianness was specified on each call to read
or write of the StreamReader / StreamWriter, but in practice
it's extremely rare for streams to have data encoded in
multiple different endiannesses, so we should optimize for the
99% use case.

This makes the code cleaner and more general, but otherwise
has NFC.

2219387eaf [PDB] Partial resubmit of r296215, which improved PDB Stream Library.
This was reverted because it was breaking some builds, and
because of incorrect error code usage.  Since the CL was
large and contained many different things, I'm resubmitting
it in pieces.

This portion is NFC, and consists of:

1) Renaming classes to follow a consistent naming convention.
2) Fixing the const-ness of the interface methods.
3) Adding detailed doxygen comments.
4) Fixing a few instances of passing `const BinaryStream& X`.  These
   are now passed as `BinaryStreamRef X`.

96678fa6d8 Revert r296215, "[PDB] General improvements to Stream library." and followings.
r296215, "[PDB] General improvements to Stream library."
r296217, "Disable BinaryStreamTest.StreamReaderObject temporarily."
r296220, "Re-enable BinaryStreamTest.StreamReaderObject."
r296244, "[PDB] Disable some tests that are breaking bots."
r296249, "Add static_cast to silence -Wc++11-narrowing."

std::errc::no_buffer_space should be used for OS-oriented errors for socket transmission.
(Seek discussions around llvm/xray.)

I could substitute s/no_buffer_space/others/g, but I revert whole them ATM.

Could we define and use LLVM errors there?

5433d115a4 [PDB] General improvements to Stream library.
This adds various new functionality and cleanup surrounding the
use of the Stream library.  Major changes include:

* Renaming of all classes for more consistency / meaningfulness
* Addition of some new methods for reading multiple values at once.
* Full suite of unit tests for reader / writer functionality.
* Full set of doxygen comments for all classes.
* Streams now store their own endianness.
* Fixed some bugs in a few of the classes that were discovered
  by the unit tests.

730695675c [CodeView] Hook up CodeViewRecordIO to type serialization path.
Previously support had been added for using CodeViewRecordIO
to read (deserialize) CodeView type records.  This patch adds
support for writing those same records.  With this patch,
reading and writing of CodeView type records finally uses a single
codepath.

d7730478c0 Add CodeViewRecordIO for reading and writing.
Using a pattern similar to that of YamlIO, this allows
us to have a single codepath for translating codeview
records to and from serialized byte streams.  The
current patch only hooks this up to the reading of
CodeView type records.  A subsequent patch will hook
it up for writing of CodeView type records, and then a
third patch will hook up the reading and writing of
CodeView symbols.

2ce5ded6d2 [pdb] Dump Module Symbols to Yaml.
This is the first step towards round-tripping symbol information,
and thusly being able to write symbol information to a PDB.

This patch writes the symbol information for each compiland to
the Yaml when running in pdb2yaml mode.  There's still some loose
ends, such as what to do about relocations (necessary in order to
print linkage names), how to print enums with friendly names, and
how to give the dumper access to the StringTable, but this is a
good first start.
