InstrProf: Test the functions in the runtime Check that the profile runtime works as expected. This tests the functions that are meant to be available to advanced users. In particular, check that the `atexit()` hook can be disabled by defining a custom `__llvm_profile_runtime` variable, that the libc dependencies are optional, and that the various functions for writing out files work for basic cases. llvm-svn: 208460
