Turn FUNCTION_ARG_PADDING into a target hook
This involved renaming the rather general-sounding "enum direction" to "enum pad_direction" to avoid a conflict with the Fortran frontend. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * coretypes.h (pad_direction): New enum. * defaults.h (DEFAULT_FUNCTION_ARG_PADDING): Delete.
