re PR fortran/90539 (481.wrf slowdown by 25% on Intel Kaby with -Ofast -march=native starting with r271377)

PR fortran/90539
* gfortran.h (gfc_has_dimen_vector_ref): Add prototype.
* trans.h (gfc_conv_subref_array_arg): Add argument check_contiguous.
(gfc_conv_is_contiguous_expr): Add prototype.
* frontend-passes.c (has_dimen_vector_ref): Remove prototype,
rename to
(gfc_has_dimen_vector_ref): New function name.
(matmul_temp_args): Use gfc_has_dimen_vector_ref.
(inline_matmul_assign): Likewise.
* trans-array.c (gfc_conv_array_parameter): Also check for absence
of a vector subscript before calling gfc_conv_subref_array_arg.
Pass additional argument to gfc_conv_subref_array_arg.
* trans-expr.c (gfc_conv_subref_array_arg): Add argument
check_contiguous. If that is true, check if the argument
is contiguous and do not repack in that case.
* trans-intrinsic.c (gfc_conv_intrinsic_is_contiguous): Split
away most of the work into, and call
(gfc_conv_intrinsic_is_coniguous_expr): New function.
