Added newsub and newclosure to PIR. Hides some implementation detail and allows IMCC to take advantage of the newsub opcode which is much more efficient than new/set_addr combination. This makes PIR orthogonal between new and newsub.
Example: PIR PASM --------------------------------------------------------------- P0 = newsub <label> ::= newsub, P0, .Sub, <label> P0 = newclosure <label> ::= newsub, P0, .Closure, <label>
This doesn't support all the variations, including continuations, the rest will come shortly.
