Don't record anonymous functions into the symbol map

Browse source 
Summary:
Although we currently forbid anonymous functions, some day we will likely permit them, and our behavior for them is wrong.

Handle them correctly rather than throwing an exception because we should be covered by D1846 against accidental use, and we won't be on PHP 5.2 forever.

Test Plan: Ran against a test file with anonymous functions. Before, it emitted a declaration of a nameless function; afterward, it did not.
