sequences in SPUDAGToDAGISel.cpp and SPU64InstrInfo.td, killing custom
DAG node types as needed.
- i64 mul is now a legal instruction, but emits an instruction sequence
that stretches tblgen and the imagination, as well as violating laws of
several small countries and most southern US states (just kidding, but
looking at a function with 80+ parameters is really weird and just plain
wrong.)
- Update tests as needed.

- 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.

- Teach SPU64InstrInfo.td about the remaining signed comparisons, update tests
accordingly.

- Fix (brcond (setq ...)) bug, where BRNZ should have been used vice BRZ.
- Kill unused/unnecessary nodes in SPUNodes.td
- Beef out the i64operations.c test harness to use a lot of unaligned
loads, test loops and LLVM loop/basic block optimizations; run the
test harness successfully on real Cell hardware.

instruction sequence and cannot ordinarily be simplified by DAGcombine
into the various target description files or SPUDAGToDAGISel.cpp.
This makes some 64-bit operations legal.
- Eliminate target-dependent ISD enums.
- Update tests.

DAGcombine's ability to find reasons to remove truncates when they were not
needed. Consequently, the CellSPU backend would produce correct, but _really
slow and horrible_, code.
Replaced with instruction sequences that do the equivalent truncation in
SPUInstrInfo.td.
- Re-examine how unaligned loads and stores work. Generated unaligned
load code has been tested on the CellSPU hardware; see the i32operations.c
and i64operations.c in CodeGen/CellSPU/useful-harnesses. (While they may be
toy test code, it does prove that some real world code does compile
correctly.)
- Fix truncating stores in bug 3193 (note: unpack_df.ll will still make llc
fault because i64 ult is not yet implemented.)
- Added i64 eq and neq for setcc and select/setcc; started new instruction
information file for them in SPU64InstrInfo.td. Additional i64 operations
should be added to this file and not to SPUInstrInfo.td.

aren't part of the test suite but are generally useful nonetheless, and can
be expanded later to test the backend against the actual Cell SPU system.
There's basically no other good place to put this code, so put it here for
the time being.
- vecoperations.c: Vector shuffles for all supported vector types, tests
for v16i8 add and multiply.
