Make LoopSimplify change conditional branches in loop exiting blocks2010-02-25T06:57:05ZDan Gohmangohman@apple.com2010-02-25T06:57:05Zurn:sha1:85669637139089eaed8def1583ac04266c9654e2
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.

it to delete loops with multiple exit conditions.

Rename the last test with .llx extension to .ll, resolve duplicate test by renaming to isnan2. Now that no test has llx ending there is no need to search for them from dg.exp too.2008-05-20T19:52:04ZGabor Greifggreif@gmail.com2008-05-20T19:52:04Zurn:sha1:722243bd402aaed698a279cb323cf37554befd53
