Original commit message:
    Reduce the memory footprint of expression classifiers

    This patch attempts to reduce the (stack) memory footprint of
    expression classifiers.  Instead of keeping space in each
    classifier for all possible error messages that will
    (potentially) be reported, if an expression turns out to be
    a pattern or a non-pattern, such error messages are placed in
    a list shared by the FunctionState and each classifier keeps a
    couple of indices in this list.  This requires that classifiers
    are used strictly in a stack-based fashion, which is also in line
    with my previous patch for revisiting non-pattern rewriting.
