glsl: Populate built-in types correctly for GLSL 3.00 ES.

This patch implements all of the built-in types for GLSL 3.00 ES.
This is almost exactly the same as the set of built-in types for GLSL
1.30, except ate 1D samplers are skipped, and samplerCubeShadow is
added.

This patch also addes an assertion so that when we add new GLSL
versions, we'll notice that we need to update the types.

In review, Eric noted:

    "This change looks correct.  The overall interaction of profiles is
    getting ugly, though.  I'm imagining a restructure of the symbol
    table population so that there's a big list of types, and each
    #version has a nice list of strings of type names copy and pasted
    out of its spec."
