I also used basic block labels when generating FDATA instead of hardcoded offsets, so the test is resilient to changes in it. I further modified main.cold to be a global symbol, so the symbol is not stripped when we run llvm-strip. We do need to run llvm-strip because I'm not declaring bb labels as temp symbols anymore (.L1 <https://reviews.llvm.org/L1>, etc), in order to use their names when generating fdata. That's the way we usually write the tests  (function names are globals, bb names are locals but non-temp so we don't need to hardcode fdata).

Thanks very much for your assistance. It has been a great help to me.
