gcc/
* coretypes.h (opt_scalar_mode): New typedef.
* gdbhooks.py (build_pretty_printers): Handle it.
* machmode.h (mode_iterator::get_2xwider): Add overload for
opt_mode<T>.
* emit-rtl.c (init_emit_once): Use opt_scalar_mode when iterating
over scalar modes.
* expr.c (convert_mode_scalar): Likewise.
* omp-low.c (omp_clause_aligned_alignment): Likewise.
* optabs.c (expand_float): Likewise.
(expand_fix): Likewise.
* tree-vect-stmts.c (vectorizable_conversion): Likewise.
gcc/c-family/
* c-common.c (c_common_fixed_point_type_for_size): Use opt_scalar_mode
for the mode iterator.
