As discussed inb4f6b26b5a"SAL_DLLPUBLIC_RTTI for proper RTTI visibility for LLVM," RTTI-based -fsanitize= checks with Clang on Linux need special precautions to make RTTI symbols visible across DSOs. The approach taken there, as well as in598d8194b0"Visible function type RTTI for Clang -fsanitize=function," was to add explicit SAL_DLLPUBLIC_RTTI annontations to relevant type definitions. However, for -fsanitize=vptr that would have required many more of those, so it appears easier to "misuse" -fsanitize-ms-compat in that case, which happens to give all RTTI symbols default visibility (while otherwise still honoring our SAL_DLLPUBLIC/PRIVATE annotations). The SAL_DLLPUBLIC_RTTI annotations from598d8194b0"Visible function type RTTI for Clang -fsanitize=function" can likely be removed again. Change-Id: Ibeff7ab8c908111a7dc66ff0677204f112b24db8
