Changes to the instruction set
==============================

1. Added Region.region to CALL instructions.
2. Added a lot of 64-bit and single-precision floating point instructions

New optimizations in the PowerPC backend
======================================
1.  Propagation of annotations.
2.  Strength reduction of unsigned 32-bit multiplication and division.
3.  NOTB folding is implemented.  For example, this combines
    NOTB with AND into NAND.
4.  3-operand floating point instructions are generated.
