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...

i386: Remove REGPARM

Use stack based calling convention (GCC default) for interfacing with
generated code instead of register based convention (regparm(3)).
