Fix the addition of Clang's profile runtime library to the link step when specifying --coverage (or related) flags. The system for doing this was based on the old LLVM-hosted profile_rt library, and hadn't been updated for Linux to use the new compiler-rt library. Also, it couldn't possibly work on multiarch or biarch systems in many cases. The whole thing now works much the same as the sanitizer libraries that are built and used out of the compiler-rt repo. Note that other target OSes haven't been updated because I don't know if they're doing anything special with the installation path of profile_rt. I suspect however that *all* of these are wrong and would encourage maintainers of each target to take a hard look at how compiler-rt runtime libraries are linked on their platforms. llvm-svn: 184666

Fix coverage-ld.c on systems with an Android linker in $PATH Summary: On my system, clang tries to invoke /path/to/arm-linux-androideabi-ld as the linker for Android, and the regex inside the test file considers this as unacceptable.
