I am submitting a patch to implement the faster intra search suggested by Steve Borho here:

https://mailman.videolan.org/pipermail/x265-devel/2014-July/004873.html

The patch is implements the faster search in slicetype.cpp. The same approach can also be used in analysis.cpp but it's a little more than a simple cut and paste though it shouldn't take long.

TEncSearch.cpp also calls intra_pred_allangs for which this is the faster alternative but at first look, TEncSearch.cpp is more complex. Depending on what is desired, either this search could greatly simplify this part of TEncSearch.cpp or it might not be applicable to what TEncSearch.cpp is doing. I will be looking into it.
