Dan Gohman 60e9b0708a Make use of getUMinFromMismatchedTypes when computing backedge-taken ...

counts for loops with multiple exits, replacing more conservative code
which only handled constants. This is derived from a patch by
Nick Lewycky.

This also fixes llc aborts in ClamAV and others, as
getUMinFromMismatchedTypes takes care of balancing the types before
working with them.
