Re-order builtin inputs to try and avoid suspected AMD driver bug

Browse Source 
* In principle the fake SV_ inputs should be able to come in any order, but it
  seems if SV_IsFrontFace is last it can get undefined/wrong results (e.g.
  returning 1 when front-face culling is enabled or vice-versa). Moving it to
  the first seems to fix the issue, and at least shouldn't make anything any
  worse.
