[68/77] Use scalar_mode for is_int_mode/is_float_mode pairs

This patch uses scalar_mode for code that operates only on MODE_INT
and MODE_FLOAT.

	* omp-expand.c (expand_omp_atomic): Use is_int_mode, is_float_mode
	and scalar_mode.
	* tree-vect-stmts.c (get_vectype_for_scalar_type_and_size): Likewise.
