[mips] Fix handling of instructions which copy to/from accumulator registers.
Expand copy instructions between two accumulator registers before callee-saved
scan is done. Handle copies between integer GPR and hi/lo registers in
MipsSEInstrInfo::copyPhysReg. Delete pseudo-copy instructions that are not
needed.
