We have changed the way that the Type Legalizer legalizes vectors. + The type legalizer now attempts to promote integer elements. + This enabled the implementation of vector-select. + Additionally, we see a performance boost on workloads which use vectors of chars and shorts, since they are now promoted + to 32-bit types, which are better supported by the SIMD instruction set. + Floating point types are still widened as before.

We have put a significant amount of work into the code generator infrastructure, which allows us to implement more aggressive algorithms and make it run faster:
