tcg: Allocate code_gen_buffer into struct tcg_region_state
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.

tcg: Return the map protection from alloc_code_gen_buffer
Change the interface from a boolean error indication to a
negative error vs a non-negative protection. For the moment
this is only interface change, not making use of the new data.

tcg: When allocating for !splitwx, begin with PROT_NONE
There's a change in mprotect() behaviour [1] in the latest macOS
on M1 and it's not yet clear if it's going to be fixed by Apple.
In this case, instead of changing permissions of N guard pages,
we change permissions of N rwx regions. The same number of
syscalls are required either way.

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.
