buildDecl was visiting all decls in source order, but the spec calls for visiting all vars and init() funcs in order, then all remaining functions. These two passes are now called buildInit(), buildFuncDecl(). + Test. Also: - Added workaround to gcimporter for Func with pkg==nil. - Prog.concreteMethods has been merged into Pkg.values. - Prog.concreteMethod() renamed declaredFunc(). - s/mfunc/obj/ (name cleanup from recent gri CL) R=gri CC=golang-dev https://golang.org/cl/12030044
