Removing the 'ess' suffix improves the ergonomics without sacrificing clarity.
Since this class is likely to be used more frequently in the future it's worth
some short term pain to fix this now.
All ExecutorProcessControl subclasses must provide an
ExecutorProcessControl::MemoryAccess object that can be used to access executor
memory from the JIT process. The EPCGenericMemoryAccess class provides an
off-the-shelf MemoryAccess implementation for JITs that do not need (or cannot
provide) a specialized MemoryAccess implementation. This simplifies the process
of creating new ExecutorProcessControl implementations.
