-finline-stringops: don't assume ptr_mode ptr in memset [PR112804]
On aarch64 -milp32, and presumably on other such targets, ptr can be
in a different mode than ptr_mode in the testcase. Cope with it.
for gcc/ChangeLog
PR target/112804
* builtins.cc (try_store_by_multiple_pieces): Use ptr's mode
for the increment.
for gcc/testsuite/ChangeLog
PR target/112804
* gcc.target/aarch64/inline-mem-set-pr112804.c: New.
