The arith assembly is big enough, and the details that you have to keep in mind are complex enough and varied enough, that it is worth using a Go program to generate the assembly. That way, all the architectures can use the same algorithms, and porting to new architectures will be easier. This is the first of a sequence of CLs to introduce a new mini-compiler for generating the arith assembly, in math/big/internal/asmgen. This CL has the basics of the compiler as well as a couple simple architectures and the generator for addVV/subVV. It does not check in the generated assembly yet. That will happen in a followup CL after the other architectures and generators have been added.
