re PR rtl-optimization/59340 (LRA enable-checking bootstrap failure since r205136) 

2013-11-29  Vladimir Makarov  <vmakarov@redhat.com>

	PR rtl-optimization/59340
	* lra.c (check_rtl): Use recog_memoized instead of insn_invalid_p.

	Revert
	2013-11-20  Robert Suchanek  <Robert.Suchanek@imgtec.com>

	* lra.c (lra): Set lra_in_progress before check_rtl call.
	* recog.c (insn_invalid_p): Add !lra_in_progress to prevent
	adding clobber regs when LRA is running.
