This PR improves type inference in general and deduces types of composite data structures in particular. Also added a way to insert a bitcast to make a fun call valid in case of arguments types mismatch due to opaque pointers type inference. The attached test `pointers/nested-struct-opaque-pointers.ll` demonstrates new capabilities: the SPIRV code emitted for this test is now (1) valid in a sense of data field types and (2) accepted by `spirv-val`. More strict LIT checks, support of more composite data structures and improvement of fun calls from the perspective of type correctness are main todo's at the moment.
