fc4eafa0f4 Make function loadImmediate a member of MipsSEInstrInfo and change it to return 
the temporary register that was used to load the immediate. Currently, it always
returns register $at, but this will change if, in the future, we decide to use 
another register.

No changes in functionality.

71746220d3 Implement MipsSERegisterInfo::eliminateCallFramePseudoInstr. The function emits 
instructions that decrement and increment the stack pointer before and after a
call when the function does not have a reserved call frame.
