PCH files don't have a module signature and LLVM uses a nonzero DWO id as
an indicator for skeleton / module CUs. This change pins the DWO id for PCH
files to a known constant value.
The correct long-term solution here is to implement a module signature
that is an actual dterministic hash (at the moment module signatures are
just random nonzero numbers) and then enable this for PCH files as well.

can be found in a module.
There are externally visible anonymous types that can be found:
typedef struct { } s; // I can be found via the typedef.
There are anonymous internal types that can be found:
namespace { struct s {}; } // I can be found by name.

until we are visiting their declcontext.
This fixes a regression introduced in r256962:
When building debug info for a typdef'd anonymous tag type, we would be
visiting the inner anonymous type first thus creating a "typedef changes
linkage of anonymous type, but linkage was already computed" error.

was visited and all decls have been merged.
We only get a single chance to emit the types for virtual classes because
CGDebugInfo::completeRequiredType() categorically doesn't complete them.

With this change, most 'g' options are rejected by CompilerInvocation.
They remain only as Driver options. The new way to request debug info
from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}"
and "-dwarf-version={2|3|4}". In the absence of a command-line option
to specify Dwarf version, the Toolchain decides it, rather than placing
Toolchain-specific logic in CompilerInvocation.
Also fix a bug in the Windows compatibility argument parsing
in which the "rightmost argument wins" principle failed.

when building a module. Clang already records the module signature when
building a skeleton CU to reference a clang module.
Matching the id in the skeleton with the one in the module allows a DWARF
consumer to verify that they found the correct version of the module
without them needing to know about the clang module format.

When -fmodule-format is set to "obj", emit debug info for all types
declared in a module or referenced by a declaration into the module's
object file container.
This patch adds support for C and C++ types.
