Fix target/101934: aarch64 memset code creates unaligned stores for
-mstrict-align

The problem here is the aarch64_expand_setmem code did not check
STRICT_ALIGNMENT if it is creating an overlapping store.
This patch adds that check and the testcase works.

gcc/ChangeLog:

PR target/101934
* config/aarch64/aarch64.c (aarch64_expand_setmem):
Check STRICT_ALIGNMENT before creating an overlapping
store.

gcc/testsuite/ChangeLog:

PR target/101934
* gcc.target/aarch64/memset-strict-align-1.c: New test.

Fixed on the trunk so far.  Will let sit on the trunk for at least a week
before backporting it.
