With the previous patch combining 3 emit functions into 1, it now makes sense to also combine the corresponding VM opcodes, which is what this patch does. This eliminates 2 opcodes which simplifies the VM and reduces code size, in bytes: bare-arm:44, minimal:64, unix(NDEBUG,x86-64):272, stmhal:92, esp8266:200. Profiling (with a simple script that creates many list/dict/set comprehensions) shows no measurable change in performance.
