02b4dd04 - [AArch64] Restrict TBI to ignore top 4 bits for Darwin targets.

[AArch64] Restrict TBI to ignore top 4 bits for Darwin targets. In order to allow arm64 code to run on MTE environments, we need to make the compiler only assume the top 4 bits can be ignored as MTE occupies the lower 4. rdar://164645323
