Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed.

Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches.

Remove the old tail duplication pass. It is not used and is unable to update
...
ssa, so it has to be run really early in the pipeline. Any replacement
should probably use the SSAUpdater.

Make LoopDeletion work on loops with multiple edges, as long as the incoming
...
values from all of the loop's exiting blocks are equal. Patch by Andrew Clinton.

Make LoopSimplify change conditional branches in loop exiting blocks
...
which branch on undef to branch on a boolean constant for the edge
exiting the loop. This helps ScalarEvolution compute trip counts for
loops.
Teach ScalarEvolution to recognize single-value PHIs, when safe, and
ForgetSymbolicName to forget such single-value PHI nodes as apprpriate
in ForgetSymbolicName.

Make LoopDeletion check the maximum backedge taken count, rather than the
...
exact backedge taken count, when checking for infinite loops. This allows
it to delete loops with multiple exit conditions.

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.
