Subject: [PATCH,rs6000] Don't restrict issue_rate for -fsched-pressure

The following patch removes the artificial restriction on issue_rate during
the first scheduling pass when -fsched-pressure is in effect.

Bootstrap/regtested on powerpc64-linux with -fsched-pressure, no new
failures.  Ok for trunk?

      * config/rs6000/rs6000.c (rs6000_issue_rate): Don't artificially
restrict
      issue_rate in first pass when scheduling for register pressure.
