<p>If you're just looking to be a client of alias analysis information, consider
using the Memory Dependence Analysis interface instead. MemDep is a lazy,
caching layer on top of alias analysis that is able to answer the question of
what preceding memory operations a given instruction depends on, either at an
intra- or inter-block level. Because of its laziness and caching
policy, using MemDep can be a significant performance win over accessing alias
analysis directly.</p>
