workaround for Intel OpCompositeConstruct bug
The SPIR-V spec permits constructing a vector from mixed vectors and
scalars, e.g. vec3(vec2, float). Intel's Vulkan driver does not handle
this correctly. We already have a workaround in place for vector
construction (writing the code as vec3(vec2.x, vec2.y, float) instead),
but missed that matrix construction can produce the same problem, as
each column requires a vector to be constructed for it. This CL extends
the workaround to handle matrix construction as well.
