Implement template instantiation for several more kinds of expressions:

  - C++ function casts, e.g., T(foo)
  - sizeof(), alignof()

More importantly, this allows us to verify that we're performing
overload resolution during template instantiation, with
argument-dependent lookup and the "cached" results of name lookup from
the template definition.
