Change the FLATTEN heuristic to "ifs with a loop with a gradient"
This heuristic makes more sense than the previous "ifs with a
discontinuous loop" as the reason we need to flatten is that we need
gradients to be in branchless code.
Change the UnrollFlatten test accordingly.
Tested with:
- the WebGL CTS
- dev.miaumiau.cat/rayTracer "Skull Demo"
- THe turbulenz engine GPU particle demo
- Lots of ShaderToy Samples (inc. Volcanic, Metropolis and Hierarchical
Voronoi)
- Google Maps Earth mode
- Lots of Chrome experiments

Implement discontinuous loops AST analysis
This will allow narrowing down which usages of
[[flatten]] and [[unroll]] are actually useful.
