This was another place where we needed to use `getConstantSubexpression` to rebuild vectors/matrices; it is a more robust approach than trying handle each ctor type individually. The fuzzer found an edge case with double-casting matrices to vectors that fell through the cracks with the original approach. In adding additional tests, I also found a case that the constant-folder seems to ignore, `bool4(x,x,x,x) == bool4(x)`. This does fold for ints and floats, so this ought to be fixable in a followup, but it's not a big deal either way; this is very unlikely to occer in real code.
