7af1c78b98 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.

9da02b844f Remove the ability for ADCE to remove unreachable blocks in loop nests, because, as Eli pointed out, SimplifyCFG already does this.

77d76b7ef7 Add support to ADCE for pruning unreachable blocks. This addresses the final 
part of PR2509.

038a8746c9 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.

722243bd40 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.

9eb883a56a 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.

OnlyReadsMemoryFns tables are dead!  We
get more, and more accurate, information
from gcc via the readnone and readonly
function attributes.

0f5aed5648 Make the llvm-runtest function much more amenable by eliminating all the 
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.

bunch of .cvsignore files to shut cvs up about known output from running
"make check".
