Subject: [PATCH 07/63] perf llvm: Make .o saving a debug message, not an info one

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Its a bit annoying to have that message, better make it a debug one.

I.e. now this message will only appear when using '-v':

  [root@...co tracebuffer]# trace -e bristot.c
  LLVM: dumping bristot.o
  ^C[root@...co tracebuffer]#
