David Majda 6ce97457bf Fix left recursion detection
So far, left recursion detector assumed that left recursion occurs only
when the recursive rule is at the very left-hand side of rule's
expression:

  start = start

This didn't catch cases like this:

  start = "a"? start

In general, if a rule reference can be reached without consuming any
input, it can lead to left recursion. This commit fixes the detector to
consider that.

Fixes #190.

David Majda 5adad3ae12 Utility functions cleanup: Split lib/utils.js
Split lib/utils.js into multiple files. Some of the functions were
generic, these were moved into files in lib/utils. Other funtions were
specific for the compiler, these were moved to files in lib/compiler.

This commit only moves functions around -- there is no renaming and
cleanup performed. Both will come later.
