d25afb579f vc1: Set the is_intra bitfield to all 1 when needed 
Keep the code as similar as possible across the codepaths to
ease spotting it for factorization.

Based on a patch from Michael Niedermayer <michaelni@gmx.at>.

b67138598c vc1: Simplify a little setting the intra variables 
The code currently set the information in at least 4 places, spare
some pointless loops.

Make the code in the loop a little uniform to make easier factorize
it out later.
