  D3D11: Translate uniform blocks to StructuredBuffer when necessary
  
  fxc exhibits slow compile performance with dynamic cbuffer indexing.
  So when a uniform block contains only one large array member, which is
  an array of structures, translate this uniform block to
  a StructuredBuffer instead.
  
  Bug: angleproject:3682
  TEST=angle_end2end_tests.UniformBufferTest.*
