Skip tests that assume 4 byte alignment for avr

gcc/testsuite

        * gcc.dg/ipa/propalign-1.c: Skip for targets with !natural_alignment_32
        and !natural_alignment_64.
        * gcc.dg/ipa/propalign-2.c: Likewise.
        * gcc.dg/ipa/propalign-3.c: Likewise.
        * gcc.dg/ipa/propalign-4.c: Likewise.
        * gcc.dg/ipa/propalign-5.c: Likewise.
        * lib/target-supports.exp
        (check_effective_target_natural_alignment_32): Add avr-*-*.
