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

cab64ae896 1. Make StoreValueToMemory a little more efficient by not requiring caller 
to make a copy of the GenericValue.

might need to zext not just trunc the value.

is larger. Adjust so that it truncates to pointer width, only if necessary.

d333ccc051 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.

a single integer field of type APInt.

7985dd51a2 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.

0e27441b52 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".

llvm-svn: 34947

6243e2253d 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.

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.
