2010-06-02	ARM: 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.
