[PATCH] Fix ipa-pure-const memory leak (PR middle-end/56461)

[Jakub Jelinek]

Hi!

The release_node hook is only called when a cgraph node is removed, not
when it merely gets ->analyzed field cleared.  If that happens on
some node that has_function_state, we leak the memory.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
ok for trunk?

        * ipa-pure-const.c (propagate): Use FOR_EACH_FUNCTION instead of
        FOR_EACH_DEFINED_FUNCTION when freeing state.
