Alex Zinenko 699a2f5373 LLVM IR lowering: support vector_type_cast ... Introduce support for lowering vector_type_cast to LLVM IR. It consists in creating a new MemRef descriptor with the base pointer with the type that corresponds to the lowered element type of the target memref. Since `vector_type_cast` does not support dynamic shapes in the target type, no dynamic size conversion is necessary. This commit goes in the opposite direction of what is expected of LLVM IR lowering: it should not be aware of all the other dialects. Instead, we should have separate definitions for conversions in a global lowering framework. However, this requires LLVM dialect to be implemented, which is currently blocked by the absence of user-defined types. Implement the lowering anyway to unblock end-to-end vectorization experiments.
