6744 protection is enabled. Use new variables to track the offset
6745 of the frame chain (and hard frame pointer) from the current
6746 stack pointer, and likewise the offset of the bottom of the
6747 register save area. Update calls to aarch64_save_callee_saves

6749 saving the FP&SIMD registers. Save the predicate registers.
