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-arm: fix a typo in comments

ARM still doesn't support 16GB buffers in 32-bit modes, replace the
16GB by 16MB in the comment.

tcg/arm: Use r6 as TCG_AREG0 to avoid clash with Thumb framepointer

On ARM, in Thumb mode r7 is used for the framepointer; this meant
that we would fail to compile in debug mode because we were using r7
for TCG_AREG0. Shift to r6 instead to avoid this clash....

tcg/arm: remove fixed map code buffer restriction

On ARM, don't map the code buffer at a fixed location, and fix up the
call/goto tcg routines to let it do long jumps.

Mapping the code buffer at a fixed address could sometimes result in it being
mapped over the top of the heap with pretty random results....

tcg: Use TCGReg for standard tcg-target entry points.

Including tcg_out_ld, tcg_out_st, tcg_out_mov, tcg_out_movi.

tcg: Standardize on TCGReg as the enum for hard registers

Most targets did not name the enum; tci used TCGRegister.

tcg/arm: Remove unused tcg_out_addi()

Remove the unused function tcg_out_addi() from the ARM TCG backend;
this fixes a compilation failure on ARM hosts with newer gcc.

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.
