revise overload resolution for splats/truncations
Allow truncations when matching arguments for intrinsic overloads. This eliminates the need for explicit scalar extractions from vectors for arguments that are scalar by nature. This encompasses any vectors passed for scalars, allowing the truncation, but emitting a warning the same as is done for other assignments of vectors to scalars. This maintains splats as the preferred transformations and promotes perfect matches to be preferred over that. This has the effect of removing the need to carefully order intrinsics to ensure that the right variant gets matched first before another one incorrectly takes its place with a faulty cast. Allowing truncations causes a problems with a small subset of intrinsics that have explicit overloads for various matrix,vector, scalar combinations. Namely the mul overloads. These could be simplified to accept a new range of template types except the dimensions need to be matched in unconventional ways. For these, the notion of uncastable or "ONLY" variants of the template/layout types are introduced. These are indicated with a trailing "!" after the parameter typename in gen_intrin_main, which directs them to an array that contains a NOCAST enum that, when encountered, will skip the attempts to splat or truncate. Fixes microsoft#7079
