We can handle all transformations (legalization) made by VC, however, in some cases, those transformations can lead to very unoptimized code, specially when unaligned loads are created and CSEd afterwards by GVN. Also, all the missed opportunities are picked by our pre-legalizer combiner. Also, toolchain tests were included for all pushed backend options.
