balazs.kilvady 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).
