re PR ipa/58106 (ICE: in ipa_edge_duplication_hook, at ipa-prop.c:2839)

2013-09-02  Martin Jambor  <mjambor@suse.cz>

	PR ipa/58106
	* ipa-prop.c (ipa_edge_duplication_hook): Always put new rdesc to the
	linked list.  When finding the correct duplicate, also consider also
	the caller in additon to its inlined_to node.

testsuite/
	* gcc.dg/ipa/pr58106.c: New test.
