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/s390: fix ld/st with CONFIG_TCG_PASS_AREG0

The load/store slow path has been broken in e141ab52d:
- We need to move 4 registers for store functions and 3 registers for
load functions and not the reverse.
- According to the s390x calling convention the arguments of a function...

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...

Rename CPUState -> CPUArchState

Scripted conversion:

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.
