Profile: Add a library for the instrumentation based profiling format

This provides a library to work with the instrumentation based
profiling format that is used by clang's -fprofile-instr-* options and
by the llvm-profdata tool. This is a binary format, rather than the
textual one that's currently in use.

The tests are in the subsequent commits that use this.
