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.

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.

- Add preliminary support for v2i32; load/store generates the right code but
there's a lot work to be done to make this vector type operational.

- Fix bugs 3194, 3195: i128 load/stores produce correct code (although, we
need to ensure that i128 is 16-byte aligned in real life), and 128 zero-
extends are supported.
- New td file: SPU128InstrInfo.td: this is where all new i128 support should
be put in the future.
- Continue to hammer on i64 operations and test cases; ensure that the only
remaining problem will be i64 mul.
llvm-svn: 61784
- Incorporate Tilmann Scheller's ISD::TRUNCATE custom lowering patch
- Update SPU calling convention info, even if it's not used yet (but can be
at some point or another)
- Ensure that any-extended f32 loads are custom lowered, especially when
they're promoted for use in printf.
