Original commit message:

    [cpu-profiler] Use instruction start as the key for the CodeMap

    Previously we used the start address of the AbstractCode object. This
    doesn't make sense for off-heap builtins, where the code isn't contained
    in the object itself. It also hides other potential problems - sometimes
    the sample.pc is inside the AbstractCode object header - this is
    never valid.

    There were a few changes necessary to make this happen:
      - Change the interface of CodeMoveEvent. Now 'to' and 'from' are both
        AbstractCode objects, which is nice because many users were taking
        'to' and adding the header offset to it to try and find the
        instruction start address. This isn't valid for off-heap builtins.
      - Fix a bug in CodeMap::MoveCode where we didn't update the CodeEntry
        object to reflect the new instruction_start.
      - Rename the 'start' field in all of the CodeEventRecord sub-classes
        to make it clear that this is the address of the first instruction.
      - Fix the confusion in RecordTickSample between 'tos' and 'pc' which
        caused pc_offset to be calculated incorrectly.
