[AArch64] Implement -fno-plt for SelectionDAG/GlobalISel
Clang sets the nonlazybind attribute for certain ObjC features. The AArch64 SelectionDAG implementation for non-intrinsic calls (46e36f09) is behind a cl option. GCC implements -fno-plt for a few ELF targets. In Clang, -fno-plt also sets the nonlazybind attribute. For SelectionDAG, make the cl option not affect ELF so that non-intrinsic calls to a dso_preemptable function use GOT. Adjust AArch64TargetLowering::LowerCall to handle intrinsic calls. For FastISel, change `fastLowerCall` to bail out when a call is due to -fno-plt. For GlobalISel, handle non-intrinsic calls in CallLowering::lowerCall and intrinsic calls in AArch64CallLowering::lowerCall (where the target-independent CallLowering::lowerCall is not called). The GlobalISel test in `call-rv-marker.ll` is therefore updated. Note: the current -fno-plt -fpic implementation does not use GOT for a preemptable function.
