tcg: Use the GDB JIT debugging interface.

This allows us to generate unwind info for the dynamicly generated
code in the code_gen_buffer. Only i386 is converted at this point.

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)).

tcg: Improve tcg_out_label and fix its usage for w64

tcg_out_label is always called with a third argument of pointer type
which was casted to tcg_target_long.

These casts can be avoided by changing the prototype of tcg_out_label.

There was also a cast to long. For most hosts with...

w64: Fix data type of parameters for flush_icache_range

flush_icache_range takes two address parameters which must be large
enough to address any address of the host.

For hosts with sizeof(unsigned long) == sizeof(void *), this patch
changes nothing. All currently supported hosts fall into this category....

tcg-i386: Introduce limited deposit support

x86 cannot provide an optimized generic deposit implementation. But at
least for a few special cases, namely for writing bits 0..7, 8..15, and
0..15, versions using only a single instruction are feasible.
Introducing such limited support improves emulating 16-bit x86 code on...
