This commit resolves an internal compiler error (ICE) on the OpenRISC (or1k) architecture related to subregister validation. Previous changes to subreg validation and mode changing triggered an ICE when the condition flag register was used in SImode. This commit updates or1k_hard_regno_mode_ok to allow the condition flag register to be used in SImode, resolving the ICEs. It was tested with an or1k Linux cross-compiler for or1k glibc builds.
