This tidies up some code that was manually constructing RuntimeDyld::SymbolInfo
instances from JITSymbols. It will save more mess in the future when
JITSymbol::getAddress is extended to return an Expected<TargetAddress> rather
than just a TargetAddress, since we'll be able to embed the error checking in
the conversion.

This chapter demonstrates lazily JITing from ASTs with the expressions being
executed on a remote machine via a TCP connection. It needs some polish, but is
substantially complete.
Currently x86-64 SysV ABI (Darwin and Linux) only, but other architectures
can be supported by changing the server code to use alternative ABI support
classes from llvm/include/llvm/ExecutionEngine/Orc/OrcABISupport.h.

Symbol resolution should be done on the top layer of the stack unless there's a
good reason to do otherwise. In this case it would have worked because
OptimizeLayer::addModuleSet eagerly passes all modules down to the
CompileLayer, meaning that searches in CompileLayer will find the definitions.
In later chapters where the top layer's addModuleSet isn't a pass-through, this
would break.

This is a work in progress - the chapter text is incomplete, though
the example code compiles and runs.
Feedback and patches are, as usual, most welcome.
