Kalle Raiskila a49d062234 Change v64 datalayout in SPU.
The SPU ABI does not mention v64, and all examples
in C suggest v128 are treated similarily to arrays, 
we use array alignment for v64 too. This makes the 
alignment of e.g. [2 x <2 x i32>] behave "intuitively"
and similar to as if the elements were e.g. i32s.

This also makes an "unaligned store" test to be 
aligned, with different (but functionally equivalent)
code generated.

Kalle Raiskila c0e9b8d8bb Change SPU register re-interpretations from OR to COPY_TO_REGCLASS instruction.
This cleans up after the mess r108567 left in the CellSPU backend.
ORCvt-instruction were used to reinterpret registers, and the ORs were then
removed by isMoveInstr(). This patch now removes 350 instrucions of format:
	or $3, $3, $3
(from the 52 testcases in CodeGen/CellSPU). One case of a nonexistant or is
checked for.

Some moves of the form 'ori $., $., 0' and 'ai $., $., 0' still remain.

Kalle Raiskila 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.

Kalle Raiskila 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.
