2010-06-02ARM: Fix the implementation of the VFP ldm and stm macroops.Gabe Black
There were four bugs in these instructions. First, the loaded value was being stored into a floating point register as floating point, changing the value as it was transfered. Second, the meaning of the "up" bit had been reversed. Third, the statically sized microop array wasn't bit enough for all possible inputs. It's now dynamically sized and should always be big enough. Fourth, the offset was stored as an unsigned 8 bit value. Negative offsets would look like moderately large positive offsets.

2010-06-02ARM: Implement the RFE instruction.Gabe Black
2010-06-02ARM: Implement the enterx and leavex instructions.Gabe Black
These enter and leave thumbEE mode. Currently thumbEE mode behaves exactly the same as Thumb mode, but at least this will make it -look- like we're enter and leaving it. The actual behavioral changes will be implemented in future changes.
2010-06-02ARM: Fix the implementation of BX to work in thumbEE mode.Gabe Black
