Debug Info testing case: move uuid-related testing to a separate file.

Seperate the parts related to uuid from debug-info-template.cpp to
debug-info-uuid.cpp since Itanium mangler does not have support for mangling
uuid yet.

Remove -fms-extensions from RUN line of debug-info-template.cpp.
RUN line of debug-info-uuid.cpp has -fms-extensions and -cxx-abi microsoft.
