[tbsaunde+gcc@tbsaunde.org]

From: Trevor Saunders <tbsaunde+gcc@tbsaunde.org>

gcc/ChangeLog:

2015-05-20  Trevor Saunders  <tbsaunde+gcc@tbsaunde.org>

	* final.c (final_scan_insn): Don't check HAVE_peephole with the
	preprocessor.
	* output.h: Likewise.
	* genconfig.c (main): Alwways define HAVE_peephole.
	* genpeep.c: Don't emit checks of HAVE_peephole.
