e747d20130 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.

3d9309c11d Fix live variables issues: 
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue.
2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register:
   = EAX, AX<imp-use,kill>
...
AX =
In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things.

c0ac2481af Check in some #ifdef'd out code switching call argument 
lowering over to SparcCallingConv.td.  We can't make the switch
yet because we can't say to pass f64 registers in 2 x i32 registers
with the td file yet.
