[PATCH 3/8] Fix usage of hard_regno_nregs before reload

[Alexander Monakov]

From: Sergey Grechanik <mouseentity@gmail.com>

This fixes one place where hard_regno_nregs is incorrectly guarded by
reload_completed (as if before reload all regs are pseudos).

	* sel-sched.c (verify_target_availability): Fix usage of
	hard_regno_nregs.
