When a type is only used as a template parameter and that type is the
only type imported from another #include'd module, no skeleton CU for
that module is generated, so a consumer doesn't know where to find the
type definition. By emitting an import declaration, we can force a
skeleton CU to be generated for each imported module.

This patch adds an early exit to CGDebugInfo::completeClassData() when
compiling with -gmodules and the to-be-completed type is available in
a clang module.

The previous condition would erroneously mark all CXXRecordDecls
that didn't have any fields as being defined in a clang module.
This patch fixes the condition to only apply to explicit template
instantiations.

instantiation is in a module.
This patch fixes the condition for determining whether the debug info for a
template instantiation will exist in an imported clang module by:
- checking whether the ClassTemplateSpecializationDecl is complete and
- checking that the instantiation was in a module by looking at the first field.
I also added a negative check to make sure that a typedef to a forward-declared
template (with the definition outside of the module) is handled correctly.

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.

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.
