d24558ac54 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.

01adb68f38 Reworked branch adding in prologue. Added check for infinite loops which are not modulo scheduled.

4b705a5897 Reworked branching so we don't handle BAs specially. It just updates the branchTO regardless of what type of branch it is.

da8a6fc7d4 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.

18118cf0c3 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.

bd82bbff7c 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.

8b938744dc 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.
