4329a7c2cf MIPS64: [turbofan] Improve changes from and to Smi. 
The instruction selection for following sequences is
improved:

  113: Word64Sar(107, 91) : Internal/Any
  114: TruncateInt64ToInt32(113) : Signed32/UntaggedSigned32
  115: ChangeInt32ToFloat64(114) : Signed32/UntaggedFloat64

8c3af6ca03 MIPS: [turbofan] Add new Float32Abs and Float64Abs operators. 
Port 9af9f1d026

Original commit message:
These operators compute the absolute floating point value of some
arbitrary input, and are implemented without any branches (i.e. using
vabs on arm, and andps/andpd on x86).

17ada20c17 MIPS64: Unify and improve Word32 compares to use same instructions as Word64 compares. 
The CL enables the same instructions are selected for Word32 and Word64 compare
operations which is possible due to a fact 32-bit inputs and produced values
are always sign-extended.
