Akira Hatanaka c0b020690b [mips] Lower EH_RETURN. 
Patch by Sasa Stankovic.

Akira Hatanaka bf493942b0 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.

Akira Hatanaka 88d76cfd7a 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.
