[PATCH] D46857: [CMake] Detect the compiler runtime and standard library

[Petr Hosek via Phabricator via llvm-commits]

One of the positive side-effects of this change is that it also avoids passing unnecessary `--rtlib=` and `--stdlib=` flags which eliminates spurious warnings in Fuchsia build that forced us to disable `-Werror`, this would affect any platform that uses non-default `--rtlib=` or `--stdlib=` values.
