Checks whether or not {@code symbol} can follow the current state in the
ATN. The behavior of this method is equivalent to the following, but is
implemented such that the complete context-sensitive follow set does not
need to be explicitly constructed.

<pre>
return getExpectedTokens().contains(symbol);
</pre>

@param symbol the symbol type to check
@return {@code true} if {@code symbol} can follow the current state in
the ATN, otherwise {@code false}.
