<div>
<pre>Many functions in llvm\include\llvm\CodeGen\BasicTTIImpl.h take pointers to
base Type as arguments and return them as results. However, these objects are
in fact required to be or guaranteed to be VectorType, and are unconditionally
casted to/from.
The amount of casting required in this file and in classes that use it would be
greatly reduced, and the ability to reason about the code would be greatly
increased if these functions operated on VectorType or its subclasses instead.</pre>
