[PATCH, obv?] Fix missing newlines from local-pure-const pass dump

[Luis Machado]

I noticed the debugging output from local-pure-const pass is missing a
newline in a couple places, leading to this:

 local analysis of main
   scanning: i ={v} 0;
    Volatile stmt is not const/pure
    Volatile operand is not const/pure  scanning: j ={v} 20;
    Volatile stmt is not const/pure
    Volatile operand is not const/pure  scanning: vol.0_10 ={v} i;
    Volatile stmt is not const/pure

It should've been:

 local analysis of main
   scanning: i ={v} 0;
    Volatile stmt is not const/pure
    Volatile operand is not const/pure
   scanning: j ={v} 20;
    Volatile stmt is not const/pure
    Volatile operand is not const/pure
   scanning: vol.0_10 ={v} i;
    Volatile stmt is not const/pure

Seems fairly obvious. OK?

gcc/ChangeLog:

        * ipa-pure-const.c (check_decl): Add missing newline.
        (state_from_flags): Likewise.
