6284 Do not try to pair SVE saves.
6285 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6286 reg_offsets. When handling the final allocation, expect the
6287 first SVE register save to be part of the initial allocation
6288 and for it to act as a probe at SP. Account for the SVE callee
6289 save area in the dump information.
6290 (aarch64_expand_prologue): Update the frame diagram. Fold the
6291 SVE callee allocation into the initial allocation if stack clash
6292 protection is enabled. Use new variables to track the offset
6293 of the frame chain (and hard frame pointer) from the current
6294 stack pointer, and likewise the offset of the bottom of the
6295 register save area. Update calls to aarch64_save_callee_saves
6296 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6297 saving the FP&SIMD registers. Save the predicate registers.
6298 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6299 into account when setting the stack pointer from the frame pointer,
6300 and when deciding whether we can inherit the initial adjustment
6301 amount from the prologue. Restore the predicate registers after
6302 the vector registers, then apply sve_callee_adjust, then restore
6303 the general registers.
