Re-appply r333147, reverted in r333152 due to a pre-existing bug. As
D47308 has been merged in r333206, the OSX issue should now be
resolved.
In many cases JIT users will know in which module a symbol
resides. Avoiding to search other modules can be more efficient. It
also allows to handle duplicate symbol names between modules.

This reverts r333147 until https://reviews.llvm.org/D47308 is ready to
be reviewed. r333147 exposed a behavioural difference between
OrcCBindingsStack::findSymbolIn() and OrcCBindingsStack::findSymbol(),
where only the latter does name mangling. After r333147 that causes a
test failure on OSX, because the new test looks for main using
findSymbolIn() but the mangled name is _main.

This reverts commit r327566, it breaks
test/ExecutionEngine/OrcMCJIT/test-global-ctors.ll.
The test doesn't crash with a stack trace, unfortunately. It merely
returns 1 as the exit code.
ASan didn't produce a report, and I reproduced this on my Linux machine
and Windows box.

Layer implementations typically mutate module state, and this is better
reflected by having layers own the Module they are operating on.

Handles were returned by addModule and used as keys for removeModule,
findSymbolIn, and emitAndFinalize. Their job is now subsumed by VModuleKeys,
which simplify resource management by providing a consistent handle across all
layers.

This patch updates the ORC layers and utilities to return and propagate
llvm::Errors where appropriate. This is necessary to allow ORC to safely handle
error cases in cross-process and remote JITing.

Revert "[ORC] Remove redundant semicolons from DEFINE_SIMPLE_CONVERSION_FUNCTIONS uses."
Revert "[ORC] Move ORC IR layer interface from addModuleSet to addModule and fix the module type as std::shared_ptr<Module>."
They broke ExecutionEngine/OrcMCJIT/test-global-ctors.ll on linux.

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.

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.
