Bringing a bit of order to symbol substitution.
Painstakingly winnowed out the most frequently duplicated code sequences
related to symbol cloning and substitution. Created canonical methods to
perform these actions and documented them. Key methods include:
def createFromClonedSymbols[T](syms: List[Symbol], tpe: Type)(creator: (List[Symbol], Type) => T): T
def deriveSymbols(syms: List[Symbol], symFn: Symbol => Symbol): List[Symbol]
def deriveType(syms: List[Symbol], symFn: Symbol => Symbol)(tpe: Type): Type
Many example usages enclosed with commit.
I did lots of timing tests, I find no material difference before and
after. Actually I won by four seconds in this incarnation:
Before - Total time: 7 minutes 55 seconds
After - Total time: 7 minutes 51 seconds
