with the newer, cleaner model. It uses the IAPrinter class to hold the information that is needed to match an instruction with its alias. This also takes into account the available features of the platform. There is one bit of ugliness. The way the logic determines if a pattern is unique is O(N**2), which is gross. But in reality, the number of items it's checking against isn't large. So while it's N**2, it shouldn't be a massive time sink. llvm-svn: 129110
