Robert Findley e74db46519 go/types: use an identifier map rather than isubst for recv type params
Receiver type parameters are the only type expressions allowed to be
blank. Previously this was handled by substitution of synthetic
non-blank names in the receiver type expression, but that introduced
problems related to AST mangling: the scope had extra elements,
Object.Name() was inaccurate, and synthetic nodes were recorded in
types.Info.

Fix this instead by recording a map of *ast.Ident->*TypeParam on the
Checker, which is read in Checker.ident to resolve blank identifiers
denoting receiver type parameters.
