X87: [turbofan] Add the RoundInt32ToFloat32 operator to turbofan.

  port e06f7d784e7a6f948ecc02ff1725578b9e9f0bda (r33347)

  original commit message:
  The new operator converts an int32 input to float32. If the input cannot
  be represented exactly in float32, the value is rounded using the
  round-ties-even rounding mode (the default rounding mode).

  I provide implementations of the new operator for x64, ia32, arm, arm64,
  mips, mips64, ppc, and ppc64.
