124294bc59 Obtain the exit function before execution just in case the module 
disappears before we get to calling the exit function.

38f6a15df6 Simplify code as a result of the change in GenericValue to have a single 
integer field of type APInt instead of different sized integer fields.

f9536330d6 Radically simplify execution. This patch gets rid of all the special 
handling for integer of various sizes. GenericValue now has just a single
integer field of type APInt. We use its facilities directly in the
execution of all instructions.

bfcd5992d8 Adjust and simplify external function processing now that GenericValue has

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
needed.

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.

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.
