  Remove dynamic indexing of matrices and vectors in HLSL
  
  Re-re-landing with fix to setting qualifiers on generated nodes. The
  previous version failed when a uniform was indexed, because it would
  set the uniform qualifier on some of the generated nodes and that
  interfered with the operation of UniformsHLSL.
  
  Re-landing after fixing D3D9 specific issues.
  
  HLSL doesn't support dynamic indexing of matrices and vectors, so replace
  that with helper functions that unroll dynamic indexing into switch/case
  and static indexing.
  
  Both the indexed vector/matrix expression and the index may have side
  effects, and these will be evaluated correctly. If necessary, index
  expressions that have side effects will be written to a temporary
  variable that will replace the index.
  
  Besides dEQP tests, this change is tested by a WebGL 2 conformance test.
  
  In the case that a dynamic index is out-of-range, the base ESSL 3.00 spec
  allows undefined behavior. KHR_robust_buffer_access_behavior adds the
  requirement that program termination should not occur and that
  out-of-range reads must return either a value from the active program's
  memory or zero, and out-of-range writes should only affect the active
  program's memory or do nothing. This patch clamps out-of-range indices so
  that either the first or last item of the matrix/vector is accessed.
  
  The code is not transformed in case the it fits within the limited subset
  of ESSL 1.00 given in Appendix A of the spec. If the code isn't within
  the restricted subset, even ESSL 1.00 shaders may require this
  workaround.
