  Mark some internal functions as not having side effects
  
  Precision emulation rounding function calls and vector/matrix dynamic
  indexing function calls now get a flag that indicates that running the
  function body does not have side effects. This avoids triggering
  asserts in OutputHLSL when these internal function calls end up on the
  right hand side of a non-unfolded logical operator.
