[11/77] Add a float_mode_for_size helper function
This provides a type-safe way to ask for a float mode and get it as a
scalar_float_mode.

gcc/
* coretypes.h (opt_scalar_float_mode): New typedef.
* machmode.h (float_mode_for_size): New function.
* emit-rtl.c (double_mode): Delete.
(init_emit_once): Use float_mode_for_size.
* stor-layout.c (layout_type): Likewise.
* gdbhooks.py (build_pretty_printer): Handle opt_scalar_float_mode.
