than a shared ObjectFile/MemoryBuffer pair.
There's no need to pre-parse the buffer into an ObjectFile before passing it
down to the linking layer, and moving the parsing into the linking layer allows
us remove the parsing code at each call site.

This resolver conforms to the LegacyJITSymbolResolver interface, and will be
replaced with a null-returning resolver conforming to the newer
orc::SymbolResolver interface in the near future. This patch renames the class
to avoid a clash.

The existing code created a JITSymbol with an invalid materializer instead,
guaranteeing a 'missing symbol' error when someone tried to materialize the
symbol.

This patch introduces RemoteObjectClientLayer and RemoteObjectServerLayer,
which can be used to forward ORC object-layer operations from a JIT stack in
the client to a JIT stack (consisting only of object-layers) in the server.
This is a new way to support remote-JITing in LLVM. The previous approach
(supported by OrcRemoteTargetClient and OrcRemoteTargetServer) used a
remote-mapping memory manager that sat "beneath" the JIT stack and sent
fully-relocated binary blobs to the server. The main advantage of the new
approach is that relocatable objects can be cached on the server and re-used
(if the code that they represent hasn't changed), whereas fully-relocated blobs
can not (since the addresses they have been permanently bound to will change
from run to run).
