First special instruction

Start Load/Store implementation

Start TextureSample

Sample progress

I/O Load/Store Progress

Rest of load/store

TODO: Currently, the generator still assumes the GLSL style of I/O attributres. On MSL, the vertex function should output a struct which contains a float4 with the required position attribute.

TextureSize and VectorExtract

Fix UserDefined IO Vars

Fix stage input struct names
