  Re^6-land "Move Uniform and UBO info to the gl::Program layer."
  
  This data was previously stored entirely in the Impl level. Move
  as much as possible to the GL level, using a read-only view in the
  Impl level. Some information in D3D-specific, and should be stored
  separately in the Impl.
  
  This patch has a lot of refactoring that splits the D3D and GL info,
  and moves as much validation as possible to the GL layer, where it
  is shared between the back-ends.
  
  Re-land with fix for dEQP unused uniforms. The fix involves storing
  a local copy of all uniform data in the GL layer. This will also
  let us validate sampler indexes during draw calls at the GL layer.
  
  Re-re-land with a fix for multiply defined symbols on Clang.
  
  Re-re-re-land with a fix for boolean uniforms and Uniform{1234}f.
  
  Re^4-land with a fix for boolean uniform arrays and UBO uniforms.
  
  Re^5-land with a fix for a test warning on Linux.
  
  Re^6-land with a fix for transposed matrix uniform arrays.
  
  BUG=angleproject:1123
  TEST=end2end_tests, bots, dEQP GLES3.ubo and GLES2.uniform_api
