[tree-ssa] use call_expr_flags more


Noticed while looking at something else.  Note that call_expr_flags
is more through than either of these places.


r~


        * tree-ssa-operands.c (get_call_flags): Remove.
        (get_expr_operands): Use call_expr_flags.
        * tree-alias-common.c (call_may_clobber): Likewise.
        (call_may_return): Likewise.
