First round of type-checking for new-expressions:  form
the appropriate slice type and check the bounds.  The
first bound must be a literal or a type with a
getArrayBoundValue method, which has the same recursive
nature as getLogicValue (i.e. it can return a type that
has a getArrayBoundValue that returns an integral type,
but that's it;  it's capped at one hop).  The rest
of the bounds must be empty (meaning a slice) or
constant under the same conditions as fixed-size
array types.
