Nick Lewycky 8e0a38f88a Add independent controls for whether GCOV profiling should emit .gcno files or 
instrument the program to emit .gcda.
TODO: we should emit slightly different .gcda files when .gcno emission is off.

Nick Lewycky c5ea8528cc Move the re-stemming function up top and use it where it's currently inlined. 
Break the arc-profile code out to a function like the notes emission code is,
and reorder the functions in the file.

The only functionality change is that we no longer modify the Module when the
Module has no debug info to use.

Nick Lewycky 966edd068f Rename LineProfiling to GCOVProfiling to more accurately represent what it 
does. Also mostly implement it. Still a work-in-progress, but generates legal
output on crafted test cases.
