[MS ABI] Form member pointers from virtual funcs overriding vbases We didn't supporting taking the address of virtual member functions which overrode a method in a virtual base. We simply need to encode the virtual base index in the member pointer. This fixes PR23452. N.B. There is no data member pointer side to this change because taking the address of a virtual bases' data member gives you a member pointer whose type is derived from the virtual bases' type, not the most derived type. llvm-svn: 236962

[MS] Don't escape MS C++ names with \01 It is not needed after LLVM r327734. Now it will be easier to copy-paste IR symbol names from Clang. llvm-svn: 327738
