8184e289db Pass sret arguments through the stack instead of through registers in Sparc backend. It makes the code generated more compliant with the sparc32 ABI.

687ae9606b SPARC backend: Modified LowerCall and LowerFormalArguments so that they use CallingConv assignments.

df75bbae94 Extend set of return registers on sparc until someone will implement MRV support there. At least, this will allow libgcc compile, however we are not ABI-compatible with stuff compiled with native gcc.

315123fb6a 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.

5a65b92830 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.
