  Generate performance warnings in HLSL translation
  
  Generate performance warnings for some code that undergoes heavy
  emulation when translated to HLSL:
  1. Dynamic indexing of vectors and matrices.
  2. Non-empty fall-through cases in switch/case.
  
  The warnings are generated only when code is translated to HLSL.
  Generating them in the parsing stage would add too much maintenance
  burden.
  
  Improves switch statement fall-through handling in cases where an
  empty fall-through case follows a non-empty one so that extra
  performance warnings are not generated.
