3ef437d137 Add a new use_iterator::atEnd() method, which allows us to shrink 
pred_iterator down to a single ivar.

33bbed8f2a Added implementation of immutable (functional) maps and sets, as 
implemented on top of a functional AVL tree.  The AVL balancing code
is inspired by the OCaml implementation of Map, which also uses a functional
AVL tree.

Documentation is currently limited and cleanups are planned, but this code
compiles and has been tested.

68e53ad6cb Add a new function tcExtract for extracting a bignum from an 
arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).

Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

643ce59495 Reimplement convertFromUnsignedInteger so it is passed a const bignum. 
It used to modify its argument in-place.

This interface is saner and the implementation more efficient.  It will
be needed for decimal->binary conversion.

ccf596a53e convertFromInteger, as originally written, expected sign-extended 
input.  APInt unfortunately zero-extends signed integers, so Dale
modified the function to expect zero-extended input.  Make this
assumption explicit in the function name.

copies. This may not be possible in case the node produces a chain value

it to be moved / cloned.
