fe5550b2cf Obtain the exit function before execution just in case the module 
disappears before we get to calling the exit function.

c764c55745 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.

40015aad5a 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.

c45e10474a Adjust and simplify external function processing now that GenericValue has 
a single integer field of type APInt.

7f68713eb8 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.

2d89fa84bc 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".

87aa65f40e 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.

b5caad1d5c 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.

42dd1e92c7 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.

d74ede70fb 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.

ec2b9a7850 Current pass manager, not the parent pass manager, assumes the role of

66e6a8229a This is the first major step of implementing PR1226. We now successfully 
scalarrepl things down to elements, but mem2reg can't promote elements that
are memset/memcpy'd.  Until then, the code is disabled "0 &&".

5fdded1d2f Add some simplifications for demanded bits, this allows instcombine to turn: 
define i64 @test(i64 %A, i32 %B) {
        %tmp12 = zext i32 %B to i64             ; <i64> [#uses=1]
        %tmp3 = shl i64 %tmp12, 32              ; <i64> [#uses=1]
        %tmp5 = add i64 %tmp3, %A               ; <i64> [#uses=1]
        %tmp6 = and i64 %tmp5, 123              ; <i64> [#uses=1]
        ret i64 %tmp6
}

into:

define i64 @test(i64 %A, i32 %B) {
        %tmp6 = and i64 %A, 123         ; <i64> [#uses=1]
        ret i64 %tmp6
}

This implements Transforms/InstCombine/add2.ll:test1

e2e13caeb2 canonicalize constants to the RHS of addc/adde. If nothing uses the carry out of 
addc, turn it into add.

This allows us to compile:

long long test(long long A, unsigned B) {
  return (A + ((long long)B << 32)) & 123;
}

into:

_test:
        movl $123, %eax
        andl 4(%esp), %eax
        xorl %edx, %edx
        ret

instead of:
_test:
        xorl %edx, %edx
        movl %edx, %eax
        addl 4(%esp), %eax   ;; add of zero
        andl $123, %eax
        ret
