tcg: Add TCG_COND_NEVER, TCG_COND_ALWAYS

There are several cases that can be handled easier inside both
translators and code generators if we have out-of-band values
for conditions. It's easy enough to handle ALWAYS and NEVER in
the natural way inside the tcg middle-end....

tcg: remove obsolete jmp op

The TCG jmp operation doesn't really make sense in the QEMU context, it
is unused, it is not implemented by some targets, and it is wrongly
implemented by some others.

This patch simply removes it.

tcg: Remove tcg_target_get_call_iarg_regs_count

The TCG targets no longer need individual implementations.

Since commit 6a18ae2d2947532d5c26439548afa0481c4529f9,
'flags' is no longer used in tcg_target_get_call_iarg_regs_count.

The remaining tcg_target_get_call_iarg_regs_count is trivial and only...

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: Fix compile breakage in tcg_dump_ops

Commit eeacee4d865 changed the syntax of tcg_dump_ops, but didn't convert
all users (notably missing the ppc ones) to it. Fix them to the new syntax.

tcg/ppc: Handle _CALL_DARWIN being undefined on Darwin

powerpc-apple-darwin9-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5577)
does not define _CALL_DARWIN, leading to unexpected behavior w.r.t.
register clobbering and stack frame layout.

Since _CALL_DARWIN is a reserved identifier, define a custom...
