Philippe Mathieu-Daudé 3bc313c4f5 target/mips: Use GPR move functions in gen_HILO1_tx79()
We have handy functions to access GPR. Use gen_store_gpr() for
Move From HI/LO Register and gen_load_gpr() for Move To opcodes.

Philippe Mathieu-Daudé b5b63d43a0 target/mips: Rename 128-bit upper halve GPR registers
TCG displays the upper halve registers with the same name
as their lower halves. Rename the upper halves with the
'[hi]' suffix.

Philippe Mathieu-Daudé cefd68f6b1 target/mips: Promote 128-bit multimedia registers as global ones
The cpu::mmr[] array contains the upper halves of 128-bit GPR
registers. While they are only used by the R5900 CPU, the
concept is generic and could be used by another MIPS implementation.

Rename 'cpu::mmr' as 'cpu::gpr_hi' and make them global.

When the code is similar to the GPR lower halves, move it
close by.

Philippe Mathieu-Daudé 1e3b675b3e target/mips: Include missing "tcg/tcg.h" header
Commit 83be6b5412 ("Fix MSA instructions LD.<B|H|W|D> on big endian
host") introduced use of typedef/prototypes declared in "tcg/tcg.h"
without including it. This was not a problem because "tcg/tcg.h" is
pulled in by "exec/cpu_ldst.h". To be able to remove this header
there, we first need to include it here in op_helper.c, else we get:

Taylor Simpson 7cf9345c95 Hexagon (target/hexagon/imported) arch import
Imported from the Hexagon architecture library
    imported/macros.def
        The macro definitions specify instruction attributes that are applied
        to each instruction that references the macro. The generator will
        recursively apply attributes to each instruction that used the macro.
    imported/allidefs.def
        Top level instruction definition file
    imported/*.idef
        Instruction definition files
        These files are input to the first phase of the generator
        (gen_semantics.c) to create a python include file with the
        instruction semantics and attributes.  The python include
        file is fed to the second phase to generate various header files.
    imported/encode*.def
        Instruction encoding bit patterns for every instruction

Taylor Simpson 66d29a5e80 Hexagon (target/hexagon) instruction/packet decode
Take the words from instruction memory and build a packet_t for TCG code
generation

The following operations are performed
    Convert the .new encoded offset to the register number of the producer
    Reorder the packet so .new producer is before consumer
    Apply constant extenders
    Separate subinsn's into two instructions
    Break compare-jumps into two instructions
    Create instructions for :endloop
