699d104906 Coalesing bug fix - now checks for the same regType instead of the same 
regClass since FP class has two reg Types.

7969ed3025 * Add better caching of data to avoid silly recusions 
* Only check to see if uses of instructions can be converted for expressions... so we don't look at all of the uses of a constant.  This was making the code unnecessarily conservative
