8bf61e8c2a Add necessary 64-bit support so that gcc frontend compiles (mostly). Current
issue is operand promotion for setcc/select... but looks like the fundamental
stuff is implemented for CellSPU.

203b2d6eed Bug fixes and updates for CellSPU, syncing up with trunk. Most notable
fixes are target-specific lowering of frame indices, fix constants generated
for the FSMBI instruction, and fixing SPUTargetLowering::computeMaskedBitsFor-
TargetNode().

79698f60c4 Add more patterns to match in the integer comparison test harnesses.
Fix bugs encountered, mostly due to range matching for immediates;
the CellSPU's 10-bit immediates are sign extended, covering a
larger range of unsigned values.

ad2715e0d7 - Fix support for "special" i64 immediates that can be loaded
using IL, ILA, et. al. v2i64 and i64 are now supported by
  the select bits (SELB) instruction.

- Add missing comparison operations (testcase forthcoming)

- More multiclass refactoring.

a59d469e9b Merge current work back to tree to minimize diffs and drift. Major highlights
for CellSPU modifications:

- SPUInstrInfo.td refactoring: "multiclass" really is _your_ friend.
- Other improvements based on refactoring effort in SPUISelLowering.cpp,
  esp. in SPUISelLowering::PerformDAGCombine(), where zero amount shifts and
  rotates are now eliminiated, other scalar-to-vector-to-scalar silliness
  is also eliminated.
- 64-bit operations are being implemented, _muldi3.c gcc runtime now
  compiles and generates the right code. More work still needs to be done.

9de5d0dd42 More CellSPU refinement and progress:
- Cleaned up custom load/store logic, common code is now shared [see note
  below], cleaned up address modes

- More test cases: various intrinsics, structure element access (load/store
  test), updated target data strings, indirect function calls.

Note: This patch contains a refactoring of the LoadSDNode and StoreSDNode
structures: they now share a common base class, LSBaseSDNode, that
provides an interface to their common functionality. There is some hackery
to access the proper operand depending on the derived class; otherwise,
to do a proper job would require finding and rearranging the SDOperands
sent to StoreSDNode's constructor. The current refactor errs on the
side of being conservatively and backwardly compatible while providing
functionality that reduces redundant code for targets where loads and
stores are custom-lowered.
