Dan Gohman 1880092722 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the 
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

Dan Gohman 9737a63ed8 Change these tests to feed the assembly files to opt directly, instead

Devang Patel c56423b500 Rewrite code that 1) filters loops and 2) calculates new loop bounds. 
This fixes many bugs. I will add more test cases in a separate check-in.

Some day, the code that manipulates CFG and updates dom. info could use refactoring help.
