re PR fortran/45513 (BOZ kinds differently handled, F2008: BOZ in bit intrinsics)

2018-12-24  Steven G. Kargl  <kargl@gcc.gnu.org>

	PR fortran/45513
	PR fortran/81509
	* check.c: Rename function gfc_check_iand to gfc_check_iand_ieor_ior.
	* check.c (boz_args_check): New function.  Check I and J not both BOZ.
	(gfc_check_dshift,gfc_check_iand_ieor_ior, gfc_check_ishft,
	 gfc_check_and, gfc_check_merge_bits): Use it.
	* check.c (gfc_check_iand_ieor_ior): Force conversion of BOZ to kind
	type of other agrument.  Remove silly GNU extension.
	(gfc_check_ieor, gfc_check_ior): Delete now unused functions.
	* intrinsic.c (add_functions): Use gfc_check_iand_ieor_ior. Wrap long
	line.
	* intrinsic.h: Rename gfc_check_iand to gfc_check_iand_ieor_ior.
	Delete prototype for bool gfc_check_ieor and gfc_check_ior
	* intrinsic.texi: Update documentation for boz-literal-constant.
