Prevents us from accepting code that can't be correctly transformed to
GLSL, like:
uniform float x;
float y = x;
(Previously, writing code like that in a runtime effect would
effectively produce the exact same code all the way through to GLSL, and
the driver would fail to compile it).

Adds trivial name mangling to the .stage output, so we can verify that
it's working in all places (declarations, references, etc). Also added
another global variable whose initializer is - in turn - another global.

Includes variables with and without initializers. Note that both the
.skvm and .stage output is incorrect right now. (No declarations for
global variables in .stage, and the initializer is dropped in .skvm).
