DECL_HARD_REGISTER only expects a VAR_DECL, so check for that first
(C++'s make_rtl_for_nonlocal_decl does that, too).

Bootstrapped/regtested on x86_64-linux, ok for trunk?

2017-03-29  Marek Polacek  <polacek@redhat.com>

	PR c/79730
	* c-decl.c (finish_decl): Check VAR_P.

	* gcc.dg/pr79730.c: New test.

OK.
