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.

tcg: fix sparc host for AREG0 free operation

e141ab52d2ea5d0bc6ad3b1ad32841127ca04adc didn't handle
the other memory access helper case, fix.

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)).

w64: Fix data type of next_tb and tcg_qemu_tb_exec

next_tb is the numeric value of a tcg target (= QEMU host) address.

Using tcg_target_ulong instead of unsigned long shows this and makes
the code portable for hosts with an unusual size of long (w64).

The type cast '(long)(next_tb & ~3)' was not needed (casting...

Fix large memory chunks allocation with tcg_malloc.

An attempt to allocate a large memory chunk after a small one resulted in
circular links in list of pools. It caused the same memory being
allocated twice for different arrays.

Now pools for large memory chunks are kept in separate list and are...

Rename CPUState -> CPUArchState

Scripted conversion:

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: 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.
