Currently the ll/sc instructions use the virtual address in both
user and system mode. Use the physical address insteead in system
mode.

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.

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
doesn't store back the TCG register to the target register after the
exception, as the TCG register doesn't exist anymore.

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.
