f9536330d6 Radically simplify execution. This patch gets rid of all the special
handling for integer of various sizes. GenericValue now has just a single

execution of all instructions.

d08050bd1e APInt's are no longer allocated on the heap because they are direct
members of GenericValue. Consequently the code to clean them up isn't

deca08d93d Remove the insufficient code in Interpreter::create that computed the
Target DataLayout incorrectly. For now, we'll trust that the module has
got the correct DataLayout. In the future, this needs to be changed to
tell the TargetData to be "current host".

8fb0f190a9 Simplify things significantly because GenericValue now has a single integer
field, of type APInt, instead of multiple integer fields. Also, get rid of
the special endianness code in StoreValueToMemory and LoadValueToMemory.
ExecutionEngine is always used to execute on the host platform so this is
now unnecessary.

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.
