- add XFAIL/UNSUPPORTED annotations for tests run wtih real MSVC - macroify usages of clang-specific attributes in asan tests - Add substitution for /Oy-/-fno-omit-frame-pointer This makes the dll_intercept_memset test work with mingw These are most of the changes that are required to get things running with MSVC, however there are some remaining build-flag tweaks. Nothing in here should be a functional change.
