GDB / SIM 7.3.1 Cosmetic patch for profile title

[John Wehle]

Currently doing:

  tomi-unknown-elf-run -v -p program

results in:

  Summary profiling results:

  Summary profiling results:

  Summary profiling results:

  Summary profiling results:

  Instruction Statistics

    Total: 6,212 insns

  ...

The issue being that "Summary profiling results" is displayed multiple
times in a row.  This patch fixes profile_info so that the title is
only displayed once.

The enclosed patch has been tested on FreeBSD with gdb configured for
tomi Borealis (a processor under development by Venray Technology).

ChangeLog:

Mon Oct 17 00:14:40 EDT 2011  John Wehle  (john@feith.com)

	* sim-profile.c (profile_info): Only print the title once.
