5fef3fd7e7 Added "padd*" support for MMX. Added MMX move stuff to X86InstrInfo so that 
moves, loads, etc. are recognized.

57322d0462 Use schedulePass() instead of assignPassManager() to add new LPPassManager. 
This ensures that require analysis info is available.

GenericValue to a temporary.

b5e0b0bc5e Make GenericeValue into a struct with a union instead of just a union. This 
allows an APInt value to be constructed. Remove all the native integer types
from the union. These are replaced with the single IntVal of type APInt.

45343b04b3 Keep track of inherited analysis. For example, if a loop pass does not 
preserve dominator info then it should update parent FPPassManager's
available analysis info to reflect this.

edbde240be Add preparePassManager() hook. This allows each pass to check whether 
current active pass manager is appropriate or not.

A loop pass may consider current LPPassManager in appropraite if loop
pass is not preserving analysis information that is used by other
passes managed by current LPPassManager. In such situation, loop pass
can pop current LPPassManager from the PMStack using this  hook
and use new LPPassManager for itself.

79495d839e Current pass manager, not the parent pass manager, assumes the role of 
last user when one of the managed pass uses info provided by parent pass
manager.

This was exposed by LPPassManager work.
