[35/77] Add uses of as_a <scalar_int_mode>
This patch adds asserting as_a <scalar_int_mode> conversions
to contexts in which the input is known to be a scalar integer mode.
In expand_divmod, op1 is always a scalar_int_mode if
op1_is_constant (but might not be otherwise).
In expand_binop, the patch reverses a < comparison in order to
avoid splitting a long line.
