X87: [turbofan] Implemented the optional Float32RoundTiesEven operator.

  port 57117b8339fe990867c4b8cc2c66f029a1a58bc3 (r32308)

  original commit message:
  The Float32RoundTiesEven operator rounds float32 numbers towards the nearest
  integer. If the distance to two integers is the same, then the result is
  the even integer. This is the default rounding mode of the ieee 754 floating
  point standard.

  I implemented the optional Float32RoundTiesEven operator on x64, ia32, arm, and arm64.
