This reverts commit eb68973c2f.
Reason for revert: ES2 conformance test checks this
Original change's description:
> Disallow matrix ctors which overflow a column.
>
> The GLSL spec allows matrix constructors containing vectors that would
> split between multiple columns of the matrix. However, in practice, this
> does not actually work well on a lot of GPUs!
>
> - "cast not allowed", "internal error":
> Tegra 3
> Quadro P400
> GTX 660
> GTX 960
> - Compiles, but generates wrong result:
> RadeonR9M470X
> RadeonHD7770
>
> Since this isn't a pattern we expect to see in user code, we now report
> it as an error at compile time. mat2(vec4) is treated as an exceptional
> case and still allowed.
