For AVX10 some of this is going to be needed too, though, hence I'm now refreshing these separately. Neither of the three is strictly a functional prereq, but two of the three introduce new functions which then are further altered while adding AVX10 (and AMX) logic. Hence until it is clear that one or more of these are strictly not needed / wanted (in this or another form), having these ahead of the actual work is preferable over accidentally losing adjustments done for AVX10 / AMX (and down the road perhaps others). 1: adjust extended leaves out of range clearing 2: shrink max_{,sub}leaf fields according to actual leaf contents 3: move bounding of max_{,sub}leaf fields to library code Jan
