[testsuite, guality] Add -fno-ipa-icf in gcc.dg/guality

Optimization fipa-icf breaks debug info (as is noted in PR63572 - "ICF
breaks user debugging experience"), which make guality tests clztest.c,
ctztest.c and sra-1.c unsupported for option combination "-O2 -flto
-fuse-linker-plugin -fno-fat-lto-objects".  F.i., in clztest.c foo and bar are
merged, and gdb can set a breakpoint on a line in foo, but trying to set a
breakpoint on a line in bar results in a breakpoint in main instead.

This patch works around the problem by adding -fno-ipa-icf (as is already done
in csttest.c and pr43077-1.c) to those testcases:
...
-UNSUPPORTED: gcc.dg/guality/clztest.c ... line . g == f
+PASS:        gcc.dg/guality/clztest.c ... line . g == f
-UNSUPPORTED: gcc.dg/guality/ctztest.c ... line . g == f
+PASS:        gcc.dg/guality/ctztest.c ... line . g == f
-UNSUPPORTED: gcc.dg/guality/sra-1.c ... line .+1 a[0] == 4
+PASS:        gcc.dg/guality/sra-1.c ... line .+1 a[0] == 4
-UNSUPPORTED: gcc.dg/guality/sra-1.c ... line . a[1] == 14
+PASS:        gcc.dg/guality/sra-1.c ... line . a[1] == 14
...

Tested on x86_64.
