staticprotectedinherited

Compare properties of symbols N1 and N2 that does not affect semantics of
symbol itself but affects semantics of its references from USED_BY (which
may be NULL if it is unknown).  If comparison is false, symbols
can still be merged but any symbols referring them can't.

If ADDRESS is true, do extra checking needed for IPA_REF_ADDR.

TODO: We can also split attributes to those that determine codegen of
a function body/variable constructor itself and those that are used when
referring to it.

while we walk the references anyway.
