Allow readonly functions to unwind exceptions. Teach
...
the optimizers about this. For example, a readonly
function with no uses cannot be removed unless it is
also marked nounwind.

Remove the ability for ADCE to remove unreachable blocks in loop nests, because, as Eli pointed out, SimplifyCFG already does this.

Replace the old ADCE implementation with a new one that more simply solves
...
the one case that ADCE catches that normal DCE doesn't: non-induction variable
loop computations.
This implementation handles this problem without using postdominators.

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.

XFAIL this test for the moment. The real solution is to prevent ADCE
...
from transforming loops and adding a separate loop pass for removing
loops with know trip counts. Until that happens, ADCE is miscompiling this code.
