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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73884 91177308-0d34-0410-b5e6-96231b3b80d8
