J frontend: lexer and the sentence parser, lowering to the shared IR.

Word formation and sentence parsing follow the model published in the J Dictionary. Words are formed left to right; a sentence is then executed right to left by pushing words onto a stack and matching the leftmost four stack slots against the parse table after every push.
