[33/77] Add a NARROWEST_INT_MODE macro
This patch replaces uses of GET_CLASS_NARROWEST_MODE (MODE_INT) with a
new NARROWEST_INT_MODE macro, which has type scalar_int_mode.

gcc/
* machmode.h (NARROWEST_INT_MODE): New macro.
* expr.c (alignment_for_piecewise_move): Use it instead of
GET_CLASS_NARROWEST_MODE (MODE_INT).
(push_block): Likewise.
* stor-layout.c (bit_field_mode_iterator::bit_field_mode_iterator):
Likewise.
* tree-vrp.c (simplify_float_conversion_using_ranges): Likewise.
gcc/ada/
* gcc-interface/decl.c (validate_size): Use NARROWEST_INT_MODE
instead of GET_CLASS_NARROWEST_MODE (MODE_INT).
