My only concern is that the feature is partially in 3.5, but a
user-facing part of that feature was changed once the freeze happened.
Eg)  #pragma clang loop unroll(enable) became  #pragma clang loop
unroll(full)

Then again, I don't imagine this is going to get so much use in the
real world that users can't do a simple grep to refactor their code
for the change.
