Comment (by rhaas):

 I unfortunately do not know exactly how vectorization affects bbox.cc,
 though it could: Integer operations vectorize, not just floating point
 operations. Low optimization levels will not auto-vectorize code, which is
 independent of Cactus'/Carpet's/Vectors' vectorization which uses the
 vector builtins. So my best guess is that "vectorization" here means the
 auto-vectorization that the compiler does on higher levels of optimization
 (the size of the ivects etc in a bbox are known at compile time so they
 seem like good candidates for vectorization).

 The original patch and comment is David Radice's.
