[patch] one more sched-vis fix


Hello,

I also need to handle SEQUENCE, of course, or slim dumping fails in
targets with branch delay slots. But who knew SEQUENCE can also appear
as a REG_NOTE value?!

The cfgrtl.c fix is purely cosmetic and obvious.

Bootstrapped&tested on powerpc64-unknown-linux-gnu. Committed as obvious.

Ciao!
Steven

       * sched-vis (print_pattern): Handle SEQUENCE also.
       * cfgrtl.c (print_rtl_with_bb): Do not print a newline between insns.
