infastructure.

Evan Cheng 44c0b4f754 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.

Chris Lattner 7d4152bda6 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.

other targets.  Use autogenerated calling conv to lower result of

Chris Lattner 49b269d780 Start moving sparc to use SparcCallingConv.td, switching over
return lowering first.  This fixes a bug where the top and bottom
of i64 values were returned in the wrong registers before.

Dale Johannesen 92dcf1e0c2 Next round of PPC32 ABI changes. Allow for gcc
behavior where a callee thinks a param will be

it doesn't have to be.  Handle complex long long
