Log:
PR c++/27115
* gimplify.c (voidify_wrapper_expr): Handle STATEMENT_LIST as a
wrapper.  Loop to handle nested wrappers.
(gimplify_bind_expr): Remove temp parameter.
(gimplify_modify_expr_rhs): Handle CLEANUP_POINT_EXPR, BIND_EXPR
and STATEMENT_LIST on the rhs.
(gimplify_statement_list): Voidify the STATEMENT_LIST.
(gimplify_expr): Pass pre_p to gimplify_statement_list.
(gimplify_target_expr): Remove special BIND_EXPR handling.
* cp/semantics.c (finish_stmt_expr_expr): Don't try to voidify here,
just leave the expression as it is.
(finish_stmt_expr): If the statement-expression has class type,
wrap it in a TARGET_EXPR.
* cp/cp-gimplify.c (cp_gimplify_init_expr): Don't bother with
CLEANUP_POINT_EXPR.
* cp/except.c (build_throw): Give the CLEANUP_POINT_EXPR void type.

for the orginal expample:
3.3.3 ICE
3.4.0 worked
3.2.2 ICE
3.0.4 ICE
2.95.3 ICE

I don't think we should call this critical as this is using an extension in the
first place and it only ICEs with the extension in fact.
