  Upstream Apple's direct-to-Metal backend: compile translator.
  
  This change is meant to merge the translator changes from Apple's
  direct-to-Metal backend. Taken from Kyle Piddington's CL:
  https://chromium-review.googlesource.com/c/angle/angle/+/2857366/
  The goal of this CL is to merge the translator code in a state that
  compiles, but not to switch the Metal backend over to use this
  translator backend yet.

  // RewriteCubeMapSamplersAs2DArray: Change samplerCube samplers to sampler2DArray, and the
  // textureCube* function calls to calls to helper functions that select the cube map face and sample
  // from the face as a 2D texture.  This emulates seamful cube map sampling in ES2 (or desktop GL 2)
  // and therefore only looks at samplerCube (i.e. not integer variants or cube arrays) and sampling
  // functions that are defined in ES GLSL 1.0 (i.e. not the cube overload of texture()).
