Summary:
Experience has shown that the functionality is useful. It makes linking
optimized clang with debug info for me a lot faster, 20s to 13s. The
type merging phase of PDB writing goes from 10s to 3s.
This removes the LLVM cl::opt and replaces it with a metadata flag.
After this change, users can do the following to use ghash:
- add -gcodeview-ghash to compiler flags
- replace /DEBUG with /DEBUG:GHASH in linker flags

Summary:
To improve CodeView quality for static member functions, we need to make the
static explicit. In addition to a small change in LLVM's CodeViewDebug to
return the appropriate MethodKind, this requires a small change in Clang to
note the staticness in the debug info metadata.

The shape is really just the number of methods in the vftable, since we
don't support 16 bit far calls. All calls are near. Encode this number
in the size of the artificial __vtbl_ptr_type DIDerivedType that we
generate. For DWARF, this will be a normal pointer, but for codeview
this will be a wide pointer that gets pattern matched into a
VFTableShape record. Insert this type into the element list of all
dynamic classes when emitting CodeView, so that the backend can emit the
shape even if the vptr lives in a primary base class.
Fixes PR28150

Another attempt at r276271, hopefully without breaking ModuleDebugInfo test.

Patch broke ModuleDebugInfo test on the build bots (but not locally). Again.

Unreferenced nested structs and classes were omitted from the debug info. In DWARF, this was intentional, to avoid bloat. But for CodeView, we want this information to be consistent with what Microsoft tools would produce and expect.

Reverting because it causes a test failure on build bots (Modules/ModuleDebugInfo.cpp). Failure does not reproduce locally.

This should work now that the LLVM-side of the change has landed successfully.

This includes nested types in the member list, even if there are no members of that type. Note that structs and classes have themselves as an "implicit struct" as the first member, so we skip implicit ones.

This won't always be enough info to call a virtual method from the
debugger, but it's a start.

We implemented the mangling for this a long time ago.
