tcg/arm: remove conditional argument for qemu_ld/st

While it make sense to pass a conditional argument to tcg_out_*()
functions as the ARM architecture allows that, it doesn't make sense
for qemu_ld/st functions. These functions use comparison instructions...

tcg/arm: bswap arguments in qemu_ld/st if needed

On big endian targets, data arguments of qemu_ld/st ops have to be
byte swapped. Two temporary registers are needed for qemu_st to do
the bswap. r0 and r1 are used in system mode, do the same in user
mode, which implies reworking the constraints....

tcg/arm: remove useless register tests in qemu_ld/st

addr_reg, data_reg and data_reg2 can't be register r0 or r1 du to the
constraints. Don't check if they equals these registers.

tcg/arm: fix argument alignment in qemu_st64

64-bit arguments should be aligned on an even register as specified
by the "Procedure Call Standard for the ARM Architecture".

tcg/arm: optimize register allocation order

The beginning of the register allocation order list on the TCG arm
target matches the list of clobbered registers. This means that when an
helper is called, there is almost always clobbered registers that have
to be spilled....

tcg/arm: don't try to load constants using pc

There is statistically almost 0 chances to use this code, so
remove it.

tcg/arm: add ext16u op

Add an ext16u op, either using the uxth instruction on ARMv6+ or two
shifts on previous ARM versions. In both cases the result use the same
number or less instructions than the pure TCG version.

Also move all sign extension code to separate functions, so that they...

tcg/arm: add bswap ops

Add an bswap16 and bswap32 ops, either using the rev and rev16
instructions on ARMv6+ or shifts and logical operations on previous
ARM versions. In both cases the result use less instructions than
the pure TCG version.

These ops are also needed by the qemu_ld/st functions....
