tcg/optimize: swap brcond/setcond arguments when possible

brcond and setcond ops are not commutative, but it's easy to compute the
new condition after swapping the arguments. Try to always put the constant
argument in second position like for commutative ops, to help backends to...

tcg/optimize: split expression simplification

Split expression simplification in multiple parts so that a given op
can appear multiple times. This patch should not change anything.

tcg: improve profiler

Now that there are two passes of optimization (optimize.c, liveness)
there is no point of outputing the statistics of the liveness part
only. Update the code to take into account both optimizations.

tcg/s390: fix ld/st with CONFIG_TCG_PASS_AREG0

The load/store slow path has been broken in e141ab52d:
- We need to move 4 registers for store functions and 3 registers for
load functions and not the reverse.
- According to the s390x calling convention the arguments of a function...

tcg/mips: fix broken CONFIG_TCG_PASS_AREG0 code

The CONFIG_TCG_PASS_AREG0 code for calling ld/st helpers was
broken in that it did not respect the ABI requirement that 64
bit values were passed in even-odd register pairs. The simplest
way to fix this is to implement some new utility functions...
