e60b5161d1 Fix a bug with insertelement on SPU. 
The previous algorithm in LowerVECTOR_SHUFFLE 
didn't check all requirements for "monotonic" shuffles.

ab49360f59 Remove all traces of v2[i,f]32 on SPU. 
The "half vectors" are now widened to full size by the legalizer.
The only exception is in parameter passing, where half vectors are 
expanded. This causes changes to some dejagnu tests.

68b3886678 Add preliminary v2f32 support for SPU. Like with v2i32, we just 
duplicate the instructions and operate on half vectors. 

Also reorder code in SPUInstrInfo.td for better coherency.

622f8eb981 Add preliminary v2i32 support for SPU backend. As there are no 
such registers in SPU, this support boils down to "emulating" 
them by duplicating instructions on the general purpose registers. 

This adds the most basic operations on v2i32: passing parameters,
addition, subtraction, multiplication and a few others.

ce97d55ad9 The hasMemory argument is irrelevant to how the argument 
for an "i" constraint should get lowered; PR 6309.  While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

f60c556b91 From Kalle Raiskila: 
"the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions:
-in vararg handling, registers are marked to be live, to not confuse the register scavenger
-function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack."

67a69dd2ed Eliminate target hook IsEligibleForTailCallOptimization. 
Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.

de5dea869f Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used. 
Note that "hasDotLocAndDotFile"-style debug info was already broken;
people wanting this functionality should implement it in the

1fbe054450 Add a bool flag to StackObjects telling whether they reference spill 
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..
