CellSPU: - Remove custom lowering for BRCOND - Add remaining functionality for branches in SPUInstrInfo, such as branch condition reversal and load/store folding. Updated BrCond test to reflect branch reversal. llvm-svn: 61597

Fix PR3274: when promoting the condition of a BRCOND node, promote from i1 all the way up to the canonical SetCC type. In order to discover an appropriate type to use, pass MVT::Other to getSetCCResultType. In order to be able to do this, change getSetCCResultType to take a type as an argument, not a value (this is also more logical). llvm-svn: 61542

CellSPU: - Fix fabs, fneg for f32 and f64. - Use BuildVectorSDNode.isConstantSplat, now that the functionality exists - Continue to improve i64 constant lowering. Lower certain special constants to the constant pool when they correspond to SPU's shufb instruction's special mask values. This avoids the overhead of performing a shuffle on a zero-filled vector just to get the special constant when the memory load suffices. llvm-svn: 67067
