  Log Message:
  [flang][hlfir] Generate explicit HLFIR type cast for implicit logical<->integer conversion.

hlfir.assign, in general, ends up calling the Assign runtime that asserts
that the types of LHS and RHS match. In case of implicit logical<->integer
conversions (allowed as an extension) the operands of hlfir.assign
have non-matching types. This change makes sure that the lowering
produces explicit type cast (either as a scalar fir.convert or
as a hlfir.elemental producing array expression).
