searching for external symbols, and fall back to the SymbolResolver::findSymbol
method if the former returns null.
This makes RuntimeDyld behave more like a static linker: Symbol definitions
from within the current module's "logical dylib" will be preferred to
external definitions. We can build on this behavior in the future to properly
support weak symbol handling.
Custom symbol resolvers that override the findSymbolInLogicalDylib method may
notice changes due to this patch. Clients who have not overridden this method
should generally be unaffected, however users of the OrcMCJITReplacement class
may notice changes.

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.

This class is turning into a useful interface, rather than an implementation
detail, so I'm dropping the 'Base' suffix.
No functional change.

Bypassing LLVM for this has a number of benefits:
1) Laziness support becomes asm-syntax agnostic (previously lazy jitting didn't
work on Windows as the resolver block was in Darwin asm).
2) For cross-process JITs, it allows resolver blocks and trampolines to be
emitted directly in the target process, reducing cross process traffic.
3) It should be marginally faster.
