("util/osdep: Avoid mprotect() RWX->NONE on Big Sur 11.2")
It took a few more patches than imagined to unify the two
places in which we manipulate the tcg code_gen buffer, but
the result is surely cleaner.
There's a lot more that could be done to clean up this part
of tcg too. I tried to not get too side-tracked, but didn't
wholly succeed.
