    OpenMP: Fix ICE in fixup_blocks_walker [PR111274]

    This ICE was caused by an invalid assumption that all BIND_EXPRs have
    a non-null BIND_EXPR_BLOCK.  In C++ these do exist and are used for
    temporaries introduced in expressions that are not full-expressions.
    Since they have no block to fix up, the traversal can just ignore
    these tree nodes.
