Hi!

An instruction with scratches is deleted during LRA inheritance,
and we ICE because restore_scratches wants to query its
lra_get_insn_recog_data even when it is a NOTE, but insn_extract
doesn't work on notes.

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

2016-03-21  Jakub Jelinek  <jakub@redhat.com>

	PR middle-end/70326
	* lra.c (restore_scratches): Ignore deleted insns.

	* gcc.dg/pr70326.c: New test.

OK.
