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

Revert "Use uint64_t for branch weights instead of uint32_t" This reverts commit 10f2a0d662d8d72eaac48d3e9b31ca8dc90df5a4. More uint64_t overflows.
