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.

Teach ScalarEvolution how to recognize another xor(and(x, C), C) case.

Fix ScalarEvolution's Xor handling to not assume that an And
...
that gets recognized with a SCEVZeroExtendExpr must be an And
with a low-bits mask. With r73540, this is no longer the case.
