[PATCH] Only handle DECL_ABSTRACT_ORIGIN for fndecls in IPA (PR ipa/60457)

[Jakub Jelinek]

Hi!

>From the comments on gcc-patches and from what the then block does
I think only FUNCTION_DECLs were meant to be handled this way, but as the
testcase shows we can trigger it even with VAR_DECLs.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for
trunk?

        * ipa.c (symtab_remove_unreachable_nodes): Don't call
        cgraph_get_create_node on VAR_DECLs.

        * g++.dg/ipa/pr60457.C: New test.
