Gabor Greif f45ff35bfe 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.

Owen Anderson 6af19fd1e2 DeadStoreElimination can treat byval parameters as if there were alloca's for the purpose of removing end-of-function stores.

Reid Spencer 951d8dc29f For PR1319: 
Upgrade to use new Tcl exec based test harness.

Reid Spencer d029c7e666 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.
