Add mode_for_int_vector helper functions
There are at least a few places that want to create an integer vector with a specified element size and element count, or to create the integer equivalent of an existing mode. This patch adds helpers for doing that. The require ()s are all used in functions that go on to emit instructions that use the result as a vector mode. 2017-09-05 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * machmode.h (mode_for_int_vector): New function. * stor-layout.c (mode_for_int_vector): Likewise. * config/aarch64/aarch64.c (aarch64_emit_approx_sqrt): Use it. * config/powerpcspe/powerpcspe.c (rs6000_do_expand_vec_perm): Likewise. * config/rs6000/rs6000.c (rs6000_do_expand_vec_perm): Likewise. * config/s390/s390.c (s390_expand_vec_compare_cc): Likewise. (s390_expand_vcond): Likewise. From-SVN: r251729
