      The compiler incorrectly modeled I16TOF32 and UI16TOF32. This had two detrimental effects:
      1. If the compiler created one of these instructions with a memory operand and gave it post-increment addressing, it could be dropped as dead code, leading to incorrect results.
      2. Some loops that should have used one of these instructions would instead sign extend the 16-bit integer and used I32TOF32 or UI32TOF32 instead.
