[llvm-commits] Patch to improve loop-simplify

[Andrew Clinton]

This patch improves the loop-simplify pass by avoiding the separation
of inner/outer loops in cases where the pass can determine that the
new outer loop would have no loop exits that are not also contained in
the inner loop.  In this case, what appeared to be a nested loop is
really just conditional control flow within a loop.

If someone could review and commit the patch that would be much appreciated.
