Mark asm statements as necessary in ipa-fnsummary

[Jan Hubicka]

Hi,
I forgot to mark asm statements as necessary in ipa-fnsummary. This should
mask failure of gcc.dg/guality/pr36728-2.c where the patch enabled
cloning which breaks debug info.

gcc/ChangeLog:

        * ipa-fnsummary.cc (find_necessary_statements): ASM statements are
        necessary.
