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).

The instruction selector now selects pseudo instructions: CompareAndBranch or TestAndBranch which are associated with their continuations so that generic code in the code generator will treat them as branch instruction and will be able to apply optimization like avoiding branches when the code can falltrhough.
