f9f43fb3a8 Cleanup autopref scheduling 
r253236 broke AArch64 bootstrap. Earlier revision r253071 changed scheduling
behaviour on AArch64 as autopref scheduling no longer checks the base.

This patch fixes the bootstrap failure and cleans up autopref scheduling.
The code is greatly simplified.  Sort accesses on the offset first, and
only if the offsets are the same fall back to other comparisons in
rank_for_schedule.  This doesn't at all restore the original behaviour
since we no longer compare the base address, but it now defines a total
sorting order.  More work will be required to improve the sorting so
that only loads/stores with the same base are affected.

acea40ac74 PR60580: Fix frame pointer option magic 
To fix PR60580 simplify the logic in aarch64_override_options_after_change_1 (). 
If the frame pointer is enabled, set it to a special value that behaves similar
to frame pointer omission.  If we don't do this all leaf functions will get a
frame pointer even if flag_omit_leaf_frame_pointer is set.

If flag_omit_frame_pointer has this special value, we must force the frame
pointer if not in a leaf function.  We also need to force it in a leaf function
if flag_omit_frame_pointer is not set or if LR is used.

Doing this allows both -fomit-frame-pointer and -fomit-leaf-frame-pointer to be
independently set and changed in each function with the expected behaviour.

160826fefd PR82687, g++.dg/asan/default-options-1.C fails with PR82575 fix 
The problem with making discarded symbols hidden is that the
non-default visibility is sticky.  When symbols other than the
__gnu_lto ones are discarded that turns out to be a bad idea.

	PR lto/82687
	PR lto/82575
	* simple-object-elf.c (simple_object_elf_copy_lto_debug_sections):
	Only make __gnu_lto symbols hidden.  Delete outdated comment.
