Tanya Lattner 91964490e2 Compare dependence analysis with llvm instructions versus machine instrutions. the problem with using machine instructions and alias analysis is that aa does not handle tmp instructions.

Tanya Lattner 87ee2ba48d Make this method non-const. Making it const causes the const version of 
getIGroup to be called instead of the non-const one.  These two methods
have (??) different behavior, so this change fixes bugs.

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

Tanya Lattner c0d9dcdfac When writing kernel, save the branches til the end. They are still put in the "right place" in the schedule, but sometimes when folding to make a kernel instructions are added between branches. This is wrong. To avoid this, we handle branches special.
