No compile-time support for constant operations yet,
just format transformations.  Make readers and
writers work.  Split constants into 2 doubles in
Legalize.

Surprisingly complicated.
Adds getTargetNode for 2 outputs, no inputs (missing).

Fix an extremely stupid bug that prevented first round of coalescing (physical registers only) from happening.

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.

- Added a function to hold the stack location 
  where GP must be stored during LowerCALL
- AsmPrinter now emits directives based on
  relocation type
- PIC_ set to default relocation type (same as GCC)

- Modified instruction format to handle pseudo instructions
- Added LoadAddr SDNode to load symbols.
