Apple Silicon has stricter rules about rwx mmap regions. They need to be created
using the MAP_JIT flag. However, the MAP_JIT seems to be incompatible with
MAP_SHARED. ZTS requires MAP_SHARED so that some threads may execute code from a
page while another writes/appends to it. We did not find another solution, other
than completely disabling JIT for Apple Silicon + ZTS.
