target-mips: fix translation of MT instructions

The translation of dmt/emt/dvpe/evpe was doing the moral equivalent of:

int x;
  ...        /* no initialization of x */
  x = f (x);

which confused later bits of TCG rather badly, leading to crashes.

Fix the helpers to only return results (those instructions have no...

target-mips: microMIPS ASE support

Add instruction decoding for the microMIPS ASE. All we do is decode and
then forward to the existing gen_* routines.

target-mips: make CP0_LLAddr register CPU dependent

Depending on the CPU, CP0_LLAddr is either read-only or read-write,
and the returned value can be shifted by a variable amount of bits.

target-mips: convert bit shuffle ops to TCG

Bit shuffle operations can be written with very few TCG instructions
(between 5 and 8), so it is worth converting them to TCG.

This code also move all bit shuffle generation code to a separate
function in order to have a cleaner exception code path, that is it...

target-mips: fix mft* helpers/call

This patch attempts to fix mft* helpers and the associated TCG calls.
mft* helpers do not take a register in argument, however:
- some helpers are called with an argument while they do not take one.
- some helpers are declared with an argument they don't use....

Use temporary registers for the MIPS FPU emulation.
