abd9b7ecb5 CodeView: Provide a .def file with the register ids
The list of register ids was previously written out in a couple of dirrent
places. This puts it in a .def file and also adds a few more registers (e.g.
the x87 regs) which should lead to more readable dumps, but I didn't include
the whole list since that seems unnecessary.

X86_MC::initLLVMToSEHAndCVRegMapping is pretty ugly, but at least it's not
relying on magic constants anymore. The TODO of using tablegen still stands.

6531ce0849 [CodeView] Fix dumping of public symbol record flags
I noticed nonsensical type information while dumping PDBs produced by
MSVC.

7f796fbab0 [CodeView] Move CodeView YAML code to ObjectYAML.
This is the beginning of an effort to move the codeview yaml
reader / writer into ObjectYAML so that it can be shared.
Currently the only consumer / producer of CodeView YAML is
llvm-pdbdump, but CodeView can exist outside of PDB files, and
indeed is put into object files and passed to the linker to
produce PDB files.  Furthermore, there are subtle differences
in the types of records that show up in object file CodeView
vs PDB file CodeView, but they are otherwise 99% the same.

By having this code in ObjectYAML, we can have llvm-pdbdump
reuse this code, while teaching obj2yaml and yaml2obj to use
this syntax for dealing with object files that can contain
CodeView.

This patch only adds support for CodeView type information
to ObjectYAML.  Subsequent patches will add support for
CodeView symbol information.

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

93ec93772b Rename some PDB classes.
We have a lot of very similarly named classes related to
dealing with module debug info.  This patch has NFC, it just
renames some classes to be more descriptive (albeit slightly
more to type).  The mapping from old to new class names is as
follows:

   Old          |        New
ModInfo         | DbiModuleDescriptor
ModuleSubstream | ModuleDebugFragment
ModStream       | ModuleDebugStream

With the corresponding Builder classes renamed accordingly.

3cf2ce528d Resubmit "Write the TPI stream from a PDB to Yaml."
The original patch was breaking some buildbots due to an
incorrect ordering of function definitions which caused some
compilers to recognize a definition but others to not.

6fc8fa35ae Revert "Write the TPI stream from a PDB to Yaml."
This is hitting a "use of undeclared identifier 'skipPadding' error
locally and on some bots.

This reverts r278869.

e8d9ec6b43 [codeview] Use one byte for S_FRAMECOOKIE CookieKind and add flags byte
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.

8fad65b692 [llvm-pdbdump] Dump CodeView line information.
This first pass only splits apart the records and dumps the line
info kinds and binary data.  Subsequent patches will parse out
the binary data into more useful information and dump it in
detail.
