After thinking about it I believe this is what is most likely
happening, and that these two new tests I added will need to be
reverted:

    compiler-rt/trunk/test/profile/instrprof-override-filename-then-reset-default.c
    compiler-rt/trunk/test/profile/instrprof-set-filename-then-reset-default.c

since they aren't writing to unique output names. These are 2 of the 4
tests added in r236056 (the other two are fine).

They can't be changed to write to a unique name since those tests were
specifically testing that the profile output name gets reset to the
default when null is passed to the profile filename setting
interfaces. The other profile tests use unique names.

Since I don't have write access yet, can someone revert those two files for me?

Thanks,
Teresa
