meta: Use a #define for the vector type to avoid %svec4 everywhere.
By adding "#define gvec4 %svec4" to the top of our fragment shader, we can write generic code without needing to specialize it to vec4, ivec4, or uvec4 via asprintf. This also makes the INT and UNSIGNED_INT merge function code identical, so I combined those two cases. It's not a big savings, but a little bit tidier. v2: Rebase on Vinson's MSVC build fixes.
