Zhi An Ng 5100c7d6a6 [x64] Use Abspd Negpd macro assembler helpers 
For Float64Abs, Float64Neg, F64x2Abs, and F64x2Neg, we can use the Abspd
and Negpd helpers. These helpers will load the necessary masks as an
ExternalReference.

We cannot do the same with AVX, since the AVX codegen can already have
one of the inputs as an Operand.
