e7816b5c9e For PR1205: 
Provide an APIntified version of MaskedValueIsZero. This will (temporarily)
cause a "defined but not used" message from the compiler. It will be used
in the next patch in this series.

Patch by Sheng Zhou.

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.

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.

addc, turn it into add.

  return (A + ((long long)B << 32)) & 123;
}

into:

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

instead of:

        movl %edx, %eax
        addl 4(%esp), %eax   ;; add of zero

9f3d738866 make better use of LCSSA information in RewriteLoopExitValues. Before, we 
would scan the entire loop body, then scan all users of instructions in the
loop, looking for users outside the loop.  Now, since we know that the
loop is in LCSSA form, we know that any users outside the loop will be LCSSA
phi nodes.  Just scan them.

This speeds up indvars significantly.
