* c-gimplify.c (gimplify_c_loop): Improve initial implementations
for loops whose conditions are known at compile-time.
* gimplify.c (append_to_statement_list_1): Remove side_effects
parameter, this function should never be called if its false.
(append_to_statement_list): Only call append_to_statement_list_1
if t is non-NULL tree with side-effects.
(append_to_statement_list_force): Likewise, if t is not NULL.
