[compiler-rt] r262723 - [ubsan/cmake] Make sure we end up adding -frtti to ubsan_type_hash_itanium.cc, even if -fno-rtti is the default for the platform

[Alexey Samsonov via llvm-commits]

I think that you should at least add -frtti to UBSAN_CXX_SOURCES for
consistency (currently, on the platforms
where -frtti is the default, we build all UBSAN_CXX_SOURCES with RTTI
enabled), but this means you'd need to
add a different flag for ubsan_type_hash_win.cc
