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.

MetalCodeGen would incorrectly identify `(someMatrix, someScalar)` as a
math operation between `someMatrix` and `someScalar` and attempt to
convert `someScalar` to a matrix. If `someScalar` was a Boolean type,
this would lead to an assertion.
The binary expression is now checked more thoroughly before converting
the scalar into a matrix.
