Correct unfinished/broken CMPU and CMP instructions and IT(TE) conditions.

The result bit 31 has not been updated when signs of inputs
did not match and signBit_r_v used in IT(TE) has not been assigned
from result when signs matched.

The CMP(U) should compare inputs => it is equivalent to RSUB
but specification of ALU_IN_NOT_REGA and CIN_ONE has been
omitted.
