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...

w64: Change data type of parameters for flush_icache_range

The TCG targets i386 and tci needed a change of the function
prototype for w64.

This change is currently not needed for the other TCG targets,
but it can be applied to avoid code differences.

tcg/s390: Remove unused tcg_out_addi()

Remove the unused function tcg_out_addi() from the s390 TCG backend;
this brings it into line with other backends.

tcg: Don't declare TCG_TARGET_REG_BITS in tcg-target.h

It is now declared for all tcg targets in tcg.h,
so the tcg target specific declarations are redundant.

tcg: Always define all of the TCGOpcode enum members.

By always defining these symbols, we can eliminate a lot of ifdefs.

To allow this to be checked reliably, the semantics of the
TCG_TARGET_HAS_* macros must be changed from def/undef to true/false.
This allows even more ifdefs to be removed, converting them into...

Delegate setup of TCG temporaries to targets

Delegate TCG temp_buf setup to targets, so that they can use a stack
frame later instead.

cpu-exec.c: avoid AREG0 use

Make functions take a parameter for CPUState instead of relying
on global env. Pass CPUState pointer to TCG prologue, which moves
it to AREG0.

Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue
change.

Revert the hacks to avoid AREG0 use on Sparc hosts....
