389dec3e7c Only generate temporaries when it makes sense
- Never for global inputs
- Otherwise only if the temporary is referenced more than once
  -> meaning it's actually caching the result of some operation

Tests updated accordingly.

a552864c3b QShaderGenerator: don't generate temporary variables for global inputs
Up until now, the QShaderGenerator would create temporary variables
for uniform, attributes, const. This change makes it use the global
inputs directly rather than relying on the intermediate properties.

b6c3f55b93 GLSL 1.00 ES must be selected using "#version 100"
I was mistaken before, the "es" part for that version isn't optional, it
*must* be omitted.
