1. Move Abspd, Negpd from MacroAssembler into TurboAssembler so that we can use it in code-generator 2. Add Absps and Negps (float32 versions of the instructions in 1) 3. Refactor SSE/AVX float32/float64 abs/neg to use these macro-assembler helpers. 4. Use these helpers in Liftoff too This has the benefit of not requiring to set up the masks in a temporary register, and loading the constants via an ExternalReference instead. It does require (in ins-sel) to have the input be in a Register, since the ExternalReference is an operand (and the instruction can only have 1 operand input).
