Atm this test in pr45882.c fails:
...
  int d = a[i];  /* { dg-final { gdb-test 16 "d" "112" } } */
...
as follows:
...
FAIL: gcc.dg/guality/pr45882.c   -O2 -flto -fuse-linker-plugin \
      -fno-fat-lto-objects  line 16 d == 112
...

In more detail, gdb fails to print the value of d:
...
Breakpoint 1, foo (i=i@entry=7, j=j@entry=7) at pr45882.c:16
16        ++v;
$1 = <optimized out>
$2 = 112
<optimized out> != 112
...

Variable d is a local variable in function foo, initialized from global array a.
When compiling, first cddce1 removes the initialization of d in foo, given
that d is not used afterwards.  Then ipa marks array a as write-only, and
removes the stores to array a in main.  This invalidates the location
expression for d, which points to a[i], so it is removed, which is why gdb
ends up printing <optimized out> for d.

This patches fixes the fail by adding attribute used to array a, preventing
array a from being marked as write-only.

Tested on x86_64.

This patch adds support for generating LDPs and STPs of Q-registers.
This allows for more compact code generation and makes better use of the ISA.

It's implemented in a straightforward way by allowing 16-byte modes in the
sched-fusion machinery and adding appropriate peepholes in aarch64-ldpstp.md
as well as the patterns themselves in aarch64-simd.md.

It adds a new no_ldp_stp_qregs tuning flag.
I use it to restrict the peepholes in aarch64-ldpstp.md from merging the
operations together into PARALLELs. I also use it to restrict the sched fusion
check that brings such loads and stores together. This is enough to avoid
forming the pairs when the tuning flag is set.

I didn't see any non-noise performance effect on SPEC2017 on Cortex-A72 and Cortex-A53.

        * config/aarch64/aarch64-tuning-flags.def (no_ldp_stp_qregs): New.
        * config/aarch64/aarch64.c (xgene1_tunings): Add
        AARCH64_EXTRA_TUNE_NO_LDP_STP_QREGS to tune_flags.
        (aarch64_mode_valid_for_sched_fusion_p):
        Allow 16-byte modes.
        (aarch64_classify_address): Allow 16-byte modes for load_store_pair_p.
        * config/aarch64/aarch64-ldpstp.md: Add peepholes for LDP STP of
        128-bit modes.
        * config/aarch64/aarch64-simd.md (load_pair<VQ:mode><VQ2:mode>):
        New pattern.
