    [x64] Consolidate SSE/AVX Float32/Float64 Abs/Neg · 9996d8ae
    Ng Zhi An authored
    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).
