rdar://131809314 Specifically threadSelfRestrictRwxToRx, threadSelfRestrictRwxToRw, and threadSelfRestrictSupported, from within FastJITPermissions.h. These functions are called whenever the JIT linker needs to write to the executable portion of memory; adding hooks at those points would help debug, especially when it's necessary to observe transitions between those states or test edge-case behavior.
