Extract the |matchesEmpty| visitor from the |reportLeftRecursion| pass

Beside the recursion detector, the visitor will also be used by infinite
loop detector.

Note the newly created |asts.matchesEmpty| function re-creates the
visitor each time it is called, which makes it slower than necessary.
This could have been worked around in various ways but I chose to defer
that optimization because real-world performance impact is small.

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.
