What flowR knows about the function name: what the built-in definitions state, filled up with what the
signature database knows (see fnInfoFromSignature). A declared signature wins, the properties of
both are joined. undefined if neither has anything to say, and also if the name resolves to a definition
in the analyzed code, which shadows any built-in.
