ARMeilleure: Hash _data pointer instead of value for Operand (#4156)

Browse source 
I noticed a weirdly high cost for dictionary accesses from MarkLabel etc. Turns out that the hash code was always the same for labels, so the whole point of having a dictionary was missed and it was putting everything in the same bucket. I made it always hash the _data pointer as that's a good source of identifiable and "random" data.
