Adrian Prantl 8f55b66a53 Module Debugging: Fine-tune the condition that determines whether a type
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.

Adrian Prantl cd975018fe Module Debugging: Make sure that anonymous tag decls that define global
variables are visited.

This shouldn't encourage anyone to put global variables into clang modules.

Adrian Prantl e5238d2a82 Module Debugging: Defer the emission of anonymous tag decls
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.

Adrian Prantl b3b821f1df Module debugging: Defer emitting tag types until their definition
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.

Adrian Prantl 4aa2b3a311 Module Debugging: Emit debug type information into clang modules.
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.
