Do not mess around with setting values within tcg_init_ctx.
Put the values into 'region' directly, which is where they
will live for the lifetime of the program.

Shortly, the full code_gen_buffer will only be visible
to region.c, so move in_code_gen_buffer out-of-line.
Move the debugging versions of tcg_splitwx_to_{rx,rw}
to region.c as well, so that the compiler gets to see
the implementation of in_code_gen_buffer.
This leaves exactly one use of in_code_gen_buffer outside
of region.c, in cpu_restore_state. Which, being on the
exception path, is not performance critical.

Return output buffer and size via output pointer arguments,
rather than returning size via tcg_ctx->code_gen_buffer_size.

Compute the value using straight division and bounds,
rather than a loop. Pass in tb_size rather than reading
from tcg_init_ctx.code_gen_buffer_size,

A size is easier to work with than an end point,
particularly during initial buffer allocation.

the max cpu value from MachineState; just remember what
we were passed in tcg_init.

Buffer management is integral to tcg. Do not leave the allocation
to code outside of tcg/. This is code movement, with further
cleanups to follow.
