Jose E. Marchesi e9bffec9af opcodes: discriminate endianness and insn-endianness in CGEN ports 
The CGEN support code in opcodes accesses instruction contents using a
couple of functions defined in cgen-opc.c: cgen_get_insn_value and
cgen_put_insn_value.  These functions use the "instruction endianness"
in the CPU description to order the read/written bytes.

The process of writing an instruction to the object file is:

  a) cgen_put_insn_value        ;; Writes out the opcodes.
  b) ARCH_cgen_insert_operand
       insert_normal
         insert_1
           cgen_put_insn_value  ;; Writes out the bytes of the
                                ;; operand.

Likewise, the process of reading an instruction from the object file
is:

  a) cgen_get_insn_value        ;; Reads the opcodes.
  b) ARCH_cgen_extract_operand
       extract_normal
         extract_1
           cgen_get_insn_value  ;; Reads in the bytes of the
                                ;; operand.

As can be seen above, cgen_{get,put}_insn_value are used to both
process the instruction opcodes (the constant fields conforming the
base instruction) and also the values of the instruction operands,
such as immediates.

This is problematic for architectures in which the endianness of
instructions is different to the endianness of data.  An example is
BPF, where instructions are always encoded big-endian but the data may
be either big or little.

This patch changes the cgen_{get,put}_insn_value functions in order to
get an extra argument with the endianness to use, and adapts the
existin callers to these functions in order to provide cd->endian or
cd->insn_endian, whatever appropriate.  Callers like extract_1 and
insert_1 pass cd->endian (since they are reading/writing operand
values) while callers reading/writing the base instruction pass
cd->insn_endian instead.

A few little adjustments have been needed in some existing CGEN based
ports:
* The BPF assembler uses cgen_put_insn_value.  It has been adapted to
  pass the new endian argument.
* The mep port has code in mep.opc that uses cgen_{get,put}_insn_value.
  It has been adapted to pass the new endianargument.  Ditto for a
  call in the assembler.

Tested with --enable-targets=all.
Regested in all supported targets.
No regressions.

This function is basically just a big switch statement. Earlier versions
used tables to look up the function to use, but
- if the table contains both assembler and disassembler functions then
the disassembler contains much of the assembler and vice-versa,
- there's a lot of inlining possibilities as things grow,
- using a switch statement avoids the function call overhead.
This function could be moved into `parse_insn_normal', but keeping it
separate makes clear the interface between `parse_insn_normal' and each of

/* Main entry point for operand extraction.
The result is <= 0 for error, >0 for success.
??? Actual values aren't well defined right now.
This function is basically just a big switch statement. Earlier versions
used tables to look up the function to use, but
- if the table contains both assembler and disassembler functions then
the disassembler contains much of the assembler and vice-versa,
- there's a lot of inlining possibilities as things grow,
- using a switch statement avoids the function call overhead.
This function could be moved into `print_insn_normal', but keeping it
separate makes clear the interface between `print_insn_normal' and each of
the handlers. */
