Some fixes for autofdo test cases

Some fixes for autofdo test cases

[Andi Kleen]

This fixes some of the problems with profile test cases running with autofdo
There are still remaining failures that need to be addressed, but this is the
low hanging fruit.

[PATCH 3/6] Add dg-final-scan-autofdo and dg-final-scan-not-autofdo

[Andi Kleen]

From: Andi Kleen <ak@linux.intel.com>

Autofdo outputs to different dump files and doesn't support some
transformation that normal profiling. Add dg-final-scan-autofdo
and dg-final-scan-not-autofdo statements to the test suite
so that the test cases can hande those cases separately.

[PATCH 6/6] Some fixes for profile test cases for autofdo

[Andi Kleen]

From: Andi Kleen <ak@linux.intel.com>

This fixes some basic issues with the profile test cases with autofdo.

- Disable checking for value transformations that autofdo does not
  support.
- Disable checking for fixed hit counts which autofdo does not support
- Enable dumping of afdo log file and check right log file.
- Increase run time of test cases to 1M iterations because autofdo needs
  a few samples to make sense of a program. The test case don't run
  noticeable slower with that.

There are still failures unfortunately, especially the indirect call
transformations do not trigger because autofdo thinks they are not hot.
This can be addressed later.

[PATCH 2/6] Don't run instrumented value profiler changes with afdo

[Andi Kleen]

From: Andi Kleen <ak@linux.intel.com>

The pass to transform gimple based on value profiling runs with autofdo
on, but currently every transformation fails. For indirect calls autofdo
does it on its own, and it doesn't suppport other value profiling. So don't
run this pass when autofdo is active. This also avoids bogus
dump file entries.

I don't think that comment is really correct.   There's all kinds of 
things going on with div/mod operations, turning string builtins into 
straightline code, etc that I see in value-prof that aren't done by 
autofdo AFAICT.

I can live with the change if the comment is corrected.

Which seems to match my assertion that value-prof does things that 
auto-prof does not.
