MIPS: sync oprand char usage between mips and micromips
We should try our best to make mips32 using the same
oprand char with micromips. So for mips32, we use:
^ is added for 5bit sa oprand for some new DSPr2 instructions:
APPEND, PREPEND, PRECR_SRA[_R].PH.W
the LSB bit is 11, like RD.
+t is removed for coprocessor 0 destination register.
'E' does the samething.
+t is now used for RX oprand for MFTR/MTTR (MT ASE)
? is added for sel oprand for MFTR/MTTR (MT ASE)
For mips32, the position of sel in MFTR/MTTR is same with mfc0 etc,
while for micromips, they are different.
We also add an extesion format of cftc2/cttc2/mftc2/mfthc2/mttc2/mtthc2:
concatenating rs with rx as the index of control or data.
