    Clear currently_expanding_gimple_stmt properly

    commit a5883ba0de68efad36db145e75c86394d8bd44ea
    Author: Michael Matz <matz@gcc.gnu.org>
    Date:   Tue Nov 24 15:37:32 2009 +0000

    introduced currently_expanding_gimple_stmt, which was set and cleared in
    expand_gimple_basic_block when expanding gimple statement to RTL.  But =
it
    isn't cleared when expand_gimple_basic_block returns inside the loop.

            PR middle-end/104721
            * cfgexpand.cc (expand_gimple_basic_block): Clear
            currently_expanding_gimple_stmt when returning inside the loop.=
