glsl_types: fix build break with intel/msvc compiler

The VECN() macro was taking advantage of a GCC specific feature that is
not available on lesser compilers, mostly for the purposes of avoiding a
macro that encoded a return statement.

But as suggested by Ian, we could just have the macro produce the entire
method body and avoid the need for this.  So let's do that instead.
