tcg/optimize: fix end of basic block detection

Commit e31b0a7c050711884ad570fe73df806520953618 fixed copy propagation on
32-bit host by restricting the copy between different types. This was the
wrong fix.

The real problem is that the all temps states should be reset at the end...

Given the copy propagation breakage on 32-bit hosts has been fixed
commit e31b0a7c050711884ad570fe73df806520953618 can be reverted.

tcg: mark set_label with TCG_OPF_BB_END flag

set_label is effectively the end of a basic block, as no optimization
can be made accross it. It was treated as such in the liveness analysis
code, but as a special case.

Mark it with TCG_OPF_BB_END flag so that this information can be used...

Remove unused CONFIG_TCG_PASS_AREG0 and dead code

Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets,
remove dead code and support for !CONFIG_TCG_PASS_AREG0 case.

Remove dyngen-exec.h and all references to it. Although included by
hw/spapr_hcall.c, it does not seem to use it....

tcg/optimize: fix if/else/break coding style

optimizer.c contains some cases were the break is appearing in both the
if and the else parts. Fix that by moving it to the outer part. Also
move some common code there.
