This commit improves the diagnostics for vector (elementwise) builtins in a couple of ways. It primarily provides more precise type-checking diagnostics for builtins with specific type requirements. Previously many builtins were receiving a catch-all diagnostic suggesting types which aren't valid. It also makes consistent the type-checking behaviour between various binary and ternary builtins. The binary builtins would check for mismatched argument types before specific type requirements, whereas ternary builtins would perform the checks in the reverse order. The binary builtins now behave as the ternary ones do.
