-// FIXME: Enable the use of TBAA. There are two known issues preventing this:
-//   1. Stack coloring does not update TBAA when merging allocas
-//   2. CGP inserts ptrtoint/inttoptr pairs when sinking address computations.
-//      Because BasicAA does not handle inttoptr, we'll often miss basic type
-//      punning idioms that we need to catch so we don't miscompile real-world
-//      code.
