In a previous patch, it was suggested to use all caps instead of
rolling caps for initialisms, so this patch changes everything
to do this.

A function may have instructions annotated with debug info without
having a subprogram.
This fixes PR28747.

TargetOptions wants the ExceptionHandling enum. Move that to
MCTargetOptions.h to avoid transitively including Dwarf.h everywhere in
clang. Now you can add a DWARF tag without a full rebuild of clang
semantic analysis.

This provides a better layering of responsibilities among different
aspects of PDB writing code. Some of the MSF related code was
contained in CodeView, and some was in PDB prior to this. Further,
we were often saying PDB when we meant MSF, and the two are
actually independent of each other since in theory you can have
other types of data besides PDB data in an MSF. So, this patch
separates the MSF specific code into its own library, with no
dependencies on anything else, and DebugInfoCodeView and
DebugInfoPDB take dependencies on DebugInfoMsf.

Added support for:
1. Multi dimension array.
2. Array of structure type, which previously was declared incompletely.
3. Dynamic size array.
4. Array where element type is a typedef, volatile or constant (this should resolve PR28311).

We emitted debug info for globals/functions as if they all had external
linkage. Instead, emit local symbol records when appropriate.

It is impossible to inherit from a union. We are missing a way to
represent this in IR for classes/structs...

Given something like:
struct S {
int a;
struct { int b; };
};
We would fail to give 'b' offset 4. Instead, we would give it the
offset it has inside of it's struct.

A namespace without a name should be written out as `anonymous
namespace' while a tag type without a name should be written out as
<unnamed-tag>.

MSVC makes up names for these anonymous structs, but we don't (yet).
Eventually Clang should use getTypedefNameForAnonDecl() to put some name
in the debug info, and we can update the test case when that happens.

We were asserting that our type records were valid when emitting
assembly, but not when emitting an object file.
I've been seeing lots of LNK1285 errors (corrupt PDB) during incremental
debug self-host builds with the MSVC linker, and hopefully this will
catch some of them earlier.

Summary:
This represents the adjustment applied to the implicit 'this' parameter
in the prologue of a virtual method in the MS C++ ABI. The adjustment is
always zero unless multiple inheritance is involved.
This increases the size of DISubprogram by 8 bytes, unfortunately. The
adjustment really is a signed 32-bit integer. If this size increase is
too much, we could probably win it back by splitting out a subclass with
info specific to virtual methods (virtuality, vindex, thisadjustment,
containingType).

CodeView need to know the offset of the storage allocation for a
bitfield. Encode this via the "extraData" field in DIDerivedType and
introduced a new flag, DIFlagBitField, to indicate whether or not a
member is a bitfield.
This fixes PR28162.

Clang emits them in reverse order to conform to the ABI, which requires
left-to-right destruction. As a result, the order doesn't fall out
naturally, and we have to sort things out in the backend.
