Thanks, Duncan.

the LowerPartSet(). It didn't handle the situation correctly when
the low, high argument values are in reverse order (low > high)
with 'Val' type i32 (a corner case).

Enable emitting of constant values in non-default address space as well. The APIs emitting constants now take an additional parameter signifying the address space in which to emit. The APIs like getData8BitsDirective() etc are made virtual enabling targets to be able to define appropirate directivers for various sizes and address spaces.

If a MachineInstr doesn't have a memoperand but has an opcode that
is known to load or store, assume its memory reference may alias
*anything*, including stack slots which the compiler completely
controls.

To partially compensate for this, teach the ScheduleDAG building
code to do basic getUnderlyingValue analysis. This greatly
reduces the number of instructions that require restrictive
dependencies. This code will need to be revisited when we start
doing real alias analysis, but it should suffice for now.

  it is.

XFAIL this test.  It only worked before because of a bug in the spill point selection code.  Not deleting because 
it should be possible to enhance the selection code to handle this in the future.

Correct the algorithms for choosing spill and restore points so that we don't try to insert loads/stores between call frame setup and the actual call.

This fixes the last known failure for the pre-alloc-splitter.
