[fortran, patch] pr31760, missing elemental applicability

[Daniel Franke]

:ADDPATCH fortran:

Although marked and documented as ELEMENTAL, BESXY and ERF functions could not 
be used with arrays as arguments. 

This patch fixes this by simply removing the scalar_check in the appropiate 
check-function. Due to this, gfc_check_g77_math1() became obsolete as the 
remaining type check for REAL is also implemented by gfc_check_fn_r().

	PR fortran/31760
	* intrinsic.c (add_functions): Replaced calls to gfc_check_g77_math1
	by gfc_check_fn_r to avoid checks for scalarity.
	* check.c (gfc_check_besn): Removed check for scalarity.
	(gfc_check_g77_math1): Removed.
	* intrinsic.h (gfc_check_g77_math1): Removed.


Ok for mainline once regtesting on i686-pc-linux-gnu finishes without 
regressions?
