expression being loop invariant is not equivalent to the property of
properly dominating the loop header.

Other optimizations have also made this optimization less important.

middle, copy the elements in two groups, rather than copying all the
elements and then doing an erase on the middle of the result. These
are SmallVectors, so we shouldn't expect to hit dynamic allocation
in the common case.

type class, so that we can adjust priorities appropriately when the
preferred type for the context and the actual type of the completion
are similar.

This gets us one step closer to parity of the cached completion
results with the non-cached completion results.

GenerateReassociations make the decision about what's interesting.
This is simpler, and it avoids an extra ScalarEvolution::getAddExpr call.

This isn't necessary, because ScalarEvolution sorts them anyway,
but it's tidier this way.

implementations of equality comparison and hash computation. This
can be used to optimize node lookup by avoiding creating lots of
temporary ID values just for hashing and comparison purposes.

- Emit a different message for out-of-bounds buffer accesses if the buffer is being written to.
