  2. Revised instruction selection for the "select" operation 

    Instead of returning an optional expression, `SelectOp.select` now
always returns a CminorSel expression.  A separate Boolean-valued
function `SelectOp.select_supported` indicates at which types "select"
is supported.

  3. Binding a list of CminorSel expressions to let-variables 

    This can be useful to avoid duplicating computations.

  4. Introduce select_long 

    Like `select` at type `Tlong`, but guaranteed to be available on all platforms, by using two `select` at type `Tint` if needed.
