[mips] Access $at only if necessary.
Summary: This patch doesn't really change the logic behind expandMemInst but it allows us to assemble .S files that use .set noat with some macros. For example: .set noat lw $k0, offset($k1) Can expand to: lui $k0, %hi(offset) addu $k0, $k0, $k1 lw $k0, %lo(offset)($k0) with no need to access $at.
