Clemens Hammacher 1a1f4e1ef4 [test] Refactor AllocateAssemblerBuffer
Refactor the AllocateAssemblerBuffer helper for the new Assembler API.
This is the only non-mechanical part, all other callsites that create
Assembler instances can be trivially changed to the new API. This will
be done in a separate CL.
