tcg: Fix documentation for tcg_constant_* vs tcg_temp_free_*
At some point during the development of tcg_constant_*, I changed
my mind about whether such temps should be able to be passed to
tcg_temp_free_*. The final version committed allows this, but the
commentary was not updated to match.

tcg: Move in_code_gen_buffer and tests to region.c
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.

tcg: Restart code generation when we run out of temps
Some large translation blocks can generate so many unique

case, longjmp back to the start of code generation and
restart with a smaller translation block.
