CL 39922 made the arm assembler concurrency-safe. This CL does the same, but for ppc64. The approach is similar: introduce ctxt9 to hold function-local state and thread it through the assembler as necessary. One race remains after this CL, similar to CL 40252. That race is conceptually unrelated to this refactoring, and will be addressed in a separate CL. Passes toolstash-check -all.
