testsuite: Add -fno-ivopts to gcc.dg/Wuse-after-free-2.c, PR108828

For cris-elf before this patch, ever since it was added,
this test gets:

Running /x/gcc/testsuite/gcc.dg/dg.exp ...
FAIL: gcc.dg/Wuse-after-free-2.c  (test for warnings, line 115)
FAIL: gcc.dg/Wuse-after-free-2.c  (test for warnings, line 116)

and comparing tree dumps with a native x86_64-pc-linux-gnu
run shows a suspicious difference in the "180t.ivopts" dump.
Indeed -fno-ivopts makes the warning appear for cris-elf
too.  It was suggested to simply add -fno-ivopts to the
test-flags, like before -fno-tree-loop-distribute-patterns
was added; thus.
