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...

tcg/ppc: Fix CONFIG_TCG_PASS_AREG0 mode

Adjust the tcg_out_qemu_{ld,st}() slow paths to pass AREG0 in r3,
based on patches by malc.

Also adjust the registers clobbered, based on patch by Alex.

tcg/ppc: Do not overwrite lower address word on Darwin and AIX

For targets where TARGET_LONG_BITS != 32, i.e. 64-bit guests,
addr_reg is moved to r4. For hosts without TCG_TARGET_CALL_ALIGN_ARGS
either data_reg2 or data_reg or a masked version thereof would overwrite...

softmmu templates: optionally pass CPUState to memory access functions

Optionally, make memory access helpers take a parameter for CPUState
instead of relying on global env.

On most targets, perform simple moves to reorder registers. On i386,
switch from regparm(3) calling convention to standard stack-based...
