9d87eb19be 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.

fe613905b3 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.

22a1cf9d3a 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.

manager.
