Use integer values for weights to prevent rounding errors.

 - This is a pretty slow / memory intensive implementation, and I will likely
   change it to an iterative model, but it works.

Don't pull vector sext through both hands of a logical operation, since doing so prevents the fusion of vector sext and setcc into vsetcc.
Add a testcase for the above transformation.
Fix a bogus use of APInt noticed while tracking this down.

that it doesn't have dangling pointers when abstract types are resolved. This
modifies it somewhat to address comments: making the "StructLayoutMap" an
anonymous structure, calling "removeAbstractTypeUser" when appropriate, and
adding asserts where helpful.
