This is the very last user of any lavc transform code.
This also *corrects* wmavoice decoding, as the previous DCT/DST
transforms were incorrect, bringing it closer to Microsoft's
own wmavoice decoder.
Note: this requires new FATE files, or for the tests to be modified
to use a target error.
Patch attached.

Use the GCC specific codepath for Clang in MSVC mode too.
This matches the condition used in a number of other places.
MSVC doesn't have a way to signal potential aliasing, while GCC
(and Clang) can use __attribute__((may_alias)) for this purpose.
When building with Clang in MSVC mode, __GNUC__

The use of RET vs BR also has microarchitectural side effects. AFAIU, RET

Hi,
Just wondering what current thoughts on the patch was. It looks as
though the change is fine, but if there is still an issue I can submit a
new patch using BTI landing pads instead.
Best regards,
Casey.
