* tree.h (expand_expr_stmt_value): Add maybe_last argument.
* c-common.h (genrtl_expr_stmt_value): Likewise.
* stmt.c (expand_expr_stmt): Pass 1 as maybe_last.
(expand_expr_stmt_value): Add maybe_last argument.
Don't warn about statement with no effect if it is the last statement
in expression statement.
* c-semantics.c (genrtl_expr_stmt): Pass 1 as maybe_last.
(genrtl_expr_stmt_value): Add maybe_last argument, pass it down to
expand_expr_stmt_value.
(expand_stmt) [EXPR_STMT]: Pass 1 as maybe_last to
genrtl_expr_stmt_value if t is the last EXPR_STMT in its scope.
* expr.c (expand_expr) [LABELED_BLOCK_EXPR, LOOP_EXPR]: Pass 1
