This updates -mcount to use the new attribute names (LLVM r318195), and switches over -finstrument-functions to also use these attributes rather than inserting instrumentation in the frontend. It also adds a new flag, -finstrument-functions-after-inlining, which makes the cygprofile instrumentation get inserted after inlining rather than before.
