Allocate Adjustors and mark them readable in two steps
This drops allocateExec for darwin, and replaces it with
a alloc, write, mark executable strategy instead. This prevents
us from trying to allocate an executable range and then write to
it, which X^W will prohibit on darwin.
This will *only* work if we can use mmap.
