[patch] print SEQUENCE of insns in sched-vis.c

[Steven Bosscher]

Hello,

sched-vis.c would print insns in a SEQUENCE as a pattern, in effect
printing only GET_CODE(insn). Fixed with this patch.

Bootstrapped&tested on powerpc64-unknown-linux-gnu and
sparc64-unknown-linux-gnu with some dump inspections to make sure
everything looks as expected now.
OK for trunk?

Ciao!
Steven
* sched-vis.c (print_pattern): Print SEQUENCE of insns as insns.
