Code completion: when completing a call to a function that comes from a generic
nominal, substitute known generic parameters if possible

This should improve code completion experience for generic containers a lot:

(swift) var a = Array<Float>()
// a : Array<Float> = []
(swift) a.
...
  Decl[InstanceMethod]/CurrNominal:   append({#val: Float#})[#Void#]
...
  Decl[InstanceMethod]/CurrNominal:   each({#f: (Float) -> Void#})[#Void#]
...
  Decl[InstanceMethod]/CurrNominal:   enumerate()[#Array<Float>#]
...
  Decl[InstanceMethod]/CurrNominal:   next()[#Float?#]
...
  Decl[InstanceMethod]/CurrNominal:   sort({#pred: (Float, Float) -> Bool#})[#Void#]
...

Only implemented for functions.  Constructors and subscripts coming soon.
