Remove the -cxx-abi command-line flag. This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

Debug Info: generate a unique identifier for C++ struct, class, union, and enum. We use CXX mangler to generate unique identifier for external C++ struct, union, class and enum. Types with unique identifier are added to retained types by DIBuilder. Testing cases are updated to reflect the unique identifier generated for types. The order of MDNodes is changed because of retained types and testing cases are updated accordingly. Testing case debug-info-uuid.cpp now emits error with Itanium mangler, since uuid is not yet handled in Itanium mangler. And it will check for the error message. llvm-svn: 189622

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. llvm-svn: 189498
