    cmd/compile: track reflect.Type.Method in deadcode · cc158403
    David Crawshaw authored
    In addition to reflect.Value.Call, exported methods can be invoked
    by the Func value in the reflect.Method struct. This CL has the
    compiler track what functions get access to a legitimate reflect.Method
    struct by looking for interface calls to either of:
    
    	Method(int) reflect.Method
    	MethodByName(string) (reflect.Method, bool)
    
    This is a little overly conservative. If a user implements a type
    with one of these methods without using the underlying calls on
    reflect.Type, the linker will assume the worst and include all
    exported methods. But it's cheap.
    
    No change to any of the binary sizes reported in cl/20483.
    
    For #14740
