AArch64: use stable sorting in generating ldp/stp
In some corner cases, we have code as below:
[base + 0x310] = A
[base + 0x320] = B
[base + 0x330] = C
[base + 0x320] = D
unstable sorting could result in wrong value in offset 0x320. The
patch fixes it by using gcc_stablesort.

* config/aarch64/aarch64.c (aarch64_gen_adjusted_ldpstp): use
gcc_stablesort.
