don't declare header-defined functions both static and inline, cont.

This fixes some header-defined functions that are undesirably declared
static and weren't caught by the "^static inline" pattern used for the
main patch r13-6096-gcb3e0eac262e55.

gcc/ChangeLog:

	* hash-table.h (gt_pch_nx(hash_table<D>)): Remove static.
	* lra-int.h (lra_change_class): Likewise.
	* recog.h (which_op_alt): Likewise.
	* sel-sched-ir.h (sel_bb_empty_or_nop_p): Declare inline
	instead of static.
