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.

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.
