Commit r267457 made a lot of type-substitutions threw off code formatting and
alignment. This patch should tidy those changes up.

This replaces use of std::error_code and ErrorOr in the ORC RPC support library
with Error and Expected. This required updating the OrcRemoteTarget API, Client,
and server code, as well as updating the Orc C API.
This patch also fixes several instances where Errors were dropped.

Fixes:
(1) Removes constexpr (unsupported in MSVC)
(2) Move constructors (remove explicitly defaulted ones)
(3) <future> - Add warning suppression for MSVC.

Three problems:
1. <future> can't be easily used. If you must use it, see
include/Support/ThreadPool.h for how.
2. constexpr problems, even after 266588.
3. Move assignment operators can't be defaulted in MSVC2013.

asynchronous call/handle. Also updates the ORC remote JIT API to use the new
scheme.
The previous version of the RPC tools only supported void functions, and
required the user to manually call a paired function to return results. This
patch replaces the Procedure typedef (which only supported void functions) with
the Function typedef which supports return values, e.g.:
Function<FooId, int32_t(std::string)> Foo;
The RPC primitives and channel operations are also expanded. RPC channels must
support four new operations: startSendMessage, endSendMessage,
startRecieveMessage and endRecieveMessage, to handle channel locking. In
addition, serialization support for tuples to RPCChannels is added to enable
multiple return values.
The RPC primitives are expanded from callAppend, call, expect and handle, to:
appendCallAsync - Make an asynchronous call to the given function.
callAsync - The same as appendCallAsync, but calls send on the channel when
done.
callSTHandling - Blocking call for single-threaded code. Wraps a call to
callAsync then waits on the result, using a user-supplied
handler to handle any callbacks from the remote.
callST - The same as callSTHandling, except that it doesn't handle
callbacks - it expects the result to be the first return.
expect and handle - as before.
handleResponse - Handle a response from the remote.
waitForResult - Wait for the response with the given sequence number to arrive.

No functional change, just a little more readable.

This patch adds utilities to ORC for managing a remote JIT target. It consists
of:
1. A very primitive RPC system for making calls over a byte-stream. See
RPCChannel.h, RPCUtils.h.
2. An RPC API defined in the above system for managing memory, looking up
symbols, creating stubs, etc. on a remote target. See OrcRemoteTargetRPCAPI.h.
3. An interface for creating high-level JIT components (memory managers,
callback managers, stub managers, etc.) that operate over the RPC API. See
OrcRemoteTargetClient.h.
4. A helper class for building servers that can handle the RPC calls. See
OrcRemoteTargetServer.h.
The system is designed to work neatly with the existing ORC components and
functionality. In particular, the ORC callback API (and consequently the
CompileOnDemandLayer) is supported, enabling lazy compilation of remote code.
Assuming this doesn't trigger any builder failures, a follow-up patch will be
committed which tests these utilities by using them to replace LLI's existing
remote-JITing demo code.
