Simplify frame layout for stack probing
This patch makes some changes to the frame layout in order to simplify
stack probing. We want to use the save of LR as a probe in any non-leaf
function. With shrinkwrapping we may only save LR before a call, so it
is useful to define a fixed location in the callee-saves. So force LR at
the bottom of the callee-saves even with -fomit-frame-pointer.
Also remove a rarely used frame layout that saves the callee-saves first
with -fomit-frame-pointer. Doing so allows the store of LR to be used as
a valid stack probe in all frames.

Improve addressing of TI/TFmode
In https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01125.html Jiong
pointed out some addressing inefficiencies due to a recent change in
regcprop (https://gcc.gnu.org/ml/gcc-patches/2017-04/msg00775.html).
This patch improves aarch64_legitimize_address_displacement to split
unaligned offsets of TImode and TFmode accesses. The resulting code
is better and no longer relies on the original regcprop optimization.
This patch uses df_read_modify_subreg_p to check whether writing
to a subreg would preserve some of the existing contents.
This has the effect of putting more emphasis on the
REGMODE_NATURAL_SIZE-based definition of whether something can be
partially modified, instead of using UNITS_PER_WORD unconditionally.
This becomes important for SVE, where UNITS_PER_WORD has no
significance for subregs of multi-register LD2/ST2, LD3/ST3 and
LD4/ST4 tuples.

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.

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.
