Combine dead-code gencode switch clauses for smaller codegen

For messages with no required fields, SET_MEMOIZED_IS_INITIALIZED is never called, see the early returns above http://google3/third_party/java_src/protobuf/current/java/com/google/protobuf/GeneratedMessageLite.java;l=1526;rcl=684621860 if we return '1'.

So we can put whatever logic in here we want, and we can avoid codegenning the 'return null' instructions.

This should generate slightly smaller dex and oat code.
