Alright, I'll add:

// Reads the thread pointer register, used for __builtin_thread_pointer.

Before the IntrinsicID check.

I don't have any particular use case for this builtin in mind on PowerPC - I added the SystemZ version for use in sanitizers, and it's already supported by ARM/AArch64, so I'm submitting versions for other arches for parity.
