[18/77] Make int_mode_for_mode return an opt_scalar_int_mode
Also use int_mode_for_mode instead of (int_)mode_for_size in cases where the requested size was the bitsize of an existing mode. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (opt_mode::else_blk): New function.
