[mips] Delete MipsFunctionInfo::EmitNOAT. Unconditionally print directive
...
"set .noat" so that the assembler doesn't issue warnings when register $AT is
used.

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.

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.
