txfm: Work around VS2017 15.6 pgo bug.

Disable optimization of fdct16_avx2 when compiling under
Microsoft Visual Studio for IX86. We've had problems with
internal compiler errors on this function under profile-guided
optimization with the 15.5 and 15.6 releases.

The pragma can be removed for version-conditioned once
Microsoft addresses the issue.
