Taylor Simpson 421b53d589 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.

/*
* Section 5.5 of the Hexagon V67 Programmer's Reference Manual
*
* Slot 1 store with slot 0 load
* A slot 1 store operation with a slot 0 load operation can appear in a packet.
* The packet attribute :mem_noshuf inhibits the instruction reordering that
* would otherwise be done by the assembler. For example:
* {
* memw(R5) = R2 // slot 1 store
* R3 = memh(R6) // slot 0 load
* }:mem_noshuf
* Unlike most packetized operations, these memory operations are not executed
* in parallel (Section 3.3.1). Instead, the store instruction in Slot 1
* effectively executes first, followed by the load instruction in Slot 0. If
* the addresses of the two operations are overlapping, the load will receive
* the newly stored data. This feature is supported in processor versions
* V65 or greater.
*
*
* For qemu, we look for a load in slot 0 when there is a store in slot 1
* in the same packet. When we see this, we call a helper that probes the
* load to make sure it doesn't fault. Then, we process the store ahead of
* the actual load.
