Follow-on patch to r197595 to complete the replacement of truncating divides
in profile scaling code with rounding divide equivalents using helper routines
in basic-block.h. 

In addition to bootstrap and profiledbootstrap builds and tests (with and
without LTO), I built and tested performance of the SPEC cpu2006 benchmarks
with FDO on a Nehalem system. I didn't see any performance changes that
looked significant.
