bbudge cf62923e3b [Turbofan] Eliminate IsOutputRegisterOf and IsOutputFPRegisterOf checks. 
- Eliminates tests for whether a fixed register needs to be preserved,
and conservatively adds a UsePosition for all fixed live ranges.

This speeds up ProcessInstructions, especially when ARM register
aliasing introduces fixed live ranges for float and SIMD 128 registers.
