ebdbed3844 Added preliminary support for iterators in ImutAVLTree. 
Implemented ImutAVLTree::isEqual.

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.

910993e8dc Change APFloat::convertFromInteger to take the incoming 
bit width instead of number of words allocated, which
makes it actually work for int->APF conversions.
Adjust callers.  Add const to one of the APInt constructors
to prevent surprising match when called with const
argument.

9e3d3abd93 Remove the assumption that FP's are either float or 
double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.

dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).
