  DebugInfo: Include template parameters for simplified template decls in type units

LLVM DebugInfo CodeGen synthesizes type declarations in type units when
referencing types that are not in type units. When those synthesized
types are templates and simplified template names (or mangled simplified
template names) are in use, the template arguments must be attached to
those declarations.

A deeper fix (with a CU or DICompositeType flag) that would also support
other uses of clang's -debug-forward-template-args (such as Sony's
platform) could/should be implemented to fix this more broadly.
