static method here.
Remove some extra blank lines.
ExecutionEngine.h: Add its prototype.
lli.cpp: Call it.
Make creation method for each type of EE into a static method of its
own subclass.
Interpreter/Interpreter.cpp: ExecutionEngine::createInterpreter -->
Interpreter::create
Interpreter/Interpreter.h: Likewise.
JIT/JIT.cpp: ExecutionEngine::createJIT --> VM::create
JIT/VM.h: Likewise.
