Hexagon (target/hexagon) Clean up handling of modifier registers
Currently, the register number (MuN) for modifier registers is the
modifier register number rather than the index into hex_gpr. This
patch changes MuN to the hex_gpr index, which is consistent with
the handling of control registers.
Note that HELPER(fcircadd) needs the CS register corresponding to the
modifier register specified in the instruction. We create a TCGv
variable "CS" to hold the value to pass to the helper.
