Rather than rename this instance, use the cast-to-void idiom
instead.  This will hopefully fix the windows buildbots.

between LLVM's ATTRIBUTE_UNUSED and gcc's which was previously
hidden due to header files being included in a lucky order.

it isn't unreachable and should not be zapped.  The check for the entry block
was missing in one case: a block containing a unwind instruction.  While there,
do some small cleanups: "M" is not a great name for a Function* (it would be
more appropriate for a Module*), change it to "Fn"; use Fn in more places.

Previously the post-RA schedulers completely ignore these dependencies since
returns, branches, etc. are all scheduling barriers. This patch model the
latencies between instructions being scheduled and the barriers. It also
handle calls by marking their register uses.
