The tool I wrote is not yet available externally. Note that you do not
need to use Perf to generate the profiles. Any tool that can emit the
simple format used by the compiler will do.

For converting Perf data, you will need a parser for perf.data and an
ELF reader to match the offsets in perf.data into the loc information
inside the binary.
