Tweak Wstringop-overflow-55.c test.
On x86-32 warn_ptrdiff_anti_range_add() and warn_int_anti_range()
degrade to the same function so ICF is folding the latter into a call
into the former. This is causing no warnings to be emitted for
warn_int_anti_range.
Fixed by passing -fno-ipa-icf.
gcc/testsuite/ChangeLog:
* gcc.dg/Wstringop-overflow-55.c: Pass -fno-ipa-icf.
