Tanya Lattner 4d0ee754e3 Fixed bug in searchPath function for finding nodes between two recurrences.
Changed dependence analyzer to only use dep distances of 2 or less.
This is experimental.

Changed MSchedGraph to be able to represent more then one BB (first steps).

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 13417b5be3 Added alias analysis.
Fixed many many bugs.
This now works on almost all Singlesource , and most of MultiSource.

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.

Tanya Lattner 201e972dc4 Reworked branch adding in prologue. Added check for infinite loops which are not modulo scheduled.

Tanya Lattner d8cc4facd0 Reworked branching so we don't handle BAs specially. It just updates the branchTO regardless of what type of branch it is.

Tanya Lattner 13c71ca7b6 Forced branches to be first to be scheduled.

Tanya Lattner ab9cf27cd0 Fixed a bug where I was trying to ModuloSchedule a loop with no instructions but a terminator.
Fixed a bug in the schedule generation that was always using the start cycle.

Tanya Lattner 7beb51cd29 Added my own defMap. Only saving values that are not loop invariant. Fixed a couple of assertions that were triggered due to registers not being allocated. These both had to do with PHINodes.

Tanya Lattner 444be61ea6 Added gross hacks such as creating my own def-use map, and picking on Instruction that I can add all my TmpInstructions to its MCFI.

Tanya Lattner ddebd1eeaa Fixed bug with infinite epilogues.
Fixed issue with generating the partial order. It now adds the nodes not in recurrences in sets for each connected component.

Tanya Lattner d38a7605d8 Checking in code that works on my simple test case. However, there is still a bug with branches that I need to fix.
