Specifically: - Start using %expect_crash. - Provide an implementation of __ubsan::getDynamicTypeInfoFromVtable for the Microsoft C++ ABI. This is all that is needed for CFI diagnostics; UBSan's -fsanitize=vptr also requires an implementation of __ubsan::checkDynamicType. - Build the sanitizer runtimes against the release version of the C runtime, even in debug builds. - Accommodate demangling differences in tests.
