[PATCH vkd3d 1/8] vkd3d-shader/hlsl: Detect missing loads on rhs when splitting copies of non-numeric types.

[Giovanni Mascellani]

From: Francisco Casas <fcasas at codeweavers.com>

Otherwise we can get failed assertions:
assert(node->type == HLSL_IR_LOAD);
because broadcasts to these types are not implemented yet.
