Reapply "[Coverage] Prevent detection of false instantiations in case of macro expansion."
The root of the problem was that findMainViewFileID(File, Function)
could return some ID for any given file, even though that file
was not the main file for that function.
This patch ensures that the result of this function is conformed
with the result of findMainViewFileID(Function).

[ORC] Generalize the ORC RPC utils to support RPC function return values and
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.

IR: Use an explicit map for debug info type uniquing
Rather than relying on the structural equivalence of DICompositeType to
merge type definitions, use an explicit map on the LLVMContext that
LLParser and BitcodeReader consult when constructing new nodes.
Each non-forward-declaration DICompositeType with a non-empty
'identifier:' field is stored/loaded from the type map, and the first
definiton will "win".
This map is opt-in: clients that expect ODR types from different modules
to be merged must call LLVMContext::ensureDITypeMap.
- Clients that just happen to load more than one Module in the same
LLVMContext won't magically merge types.
- Clients (like LTO) that want to continue to merge types based on ODR
identifiers should opt-in immediately.
I have updated LTOCodeGenerator.cpp, the two "linking" spots in
gold-plugin.cpp, and llvm-link (unless -disable-debug-info-type-map) to
set this.
With this in place, it will be straightforward to remove the DITypeRef

than pointing at them directly).

ValueMapper: Separate mapping of distinct and uniqued nodes (again)
Since the result of a mapped distinct node is known up front, it's more
efficient to map them separately from uniqued nodes. This commit pulls
them out of the post-order traversal and stores them in a worklist to be
remapped at the top-level.
This is essentially reapplying r244181 ("ValueMapper: Rotate distinct
node remapping algorithm") to the new iterative algorithm from r265456
("ValueMapper: Rewrite Mapper::mapMetadata without recursion").
Now that the traversal logic only handles uniqued MDNodes, it's much
simpler to inline it all into MDNodeMapper::createPOT (I've killed the
MDNodeMapper::push and MDNodeMapper::tryToPop helpers and localized the
traversal worklist).
The resulting high-level algorithm for MDNodeMapper::map now looks like
this:
- Distinct nodes are immediately mapped and added to
MDNodeMapper::DistinctWorklist using MDNodeMapper::mapDistinctNode.
- Uniqued nodes are mapped via MDNodeMapper::mapTopLevelUniquedNode,
which traverses the transitive uniqued subgraph of a node to
calculate uniqued node mappings in bulk.
- This is a simplified version of MDNodeMapper::map from before
this commit (originally r265456) that doesn't traverse through
any distinct nodes.
- Distinct nodes are added to MDNodeMapper::DistinctWorklist via
MDNodeMapper::mapDistinctNode.
- This uses MDNodeMapper::createPOT to fill a
MDNodeMapper::UniquedGraph (a post-order traversal and side
table), UniquedGraph::propagateChanges to track which uniqued
nodes need to change, and MDNodeMapper::mapNodesInPOT to create
the uniqued nodes.
- Placeholders for forward references are now only needed when
there's a uniquing cycle (a cycle of uniqued nodes unbroken by
distinct nodes). This is the key functionality change that
we're reintroducing (from r244181). As of r265456, a temporary
forward reference might be needed for any cycle that involved
uniqued nodes.
- After mapping the first node appropriately, MDNodeMapper::map works
through MDNodeMapper::DistinctWorklist. For each distinct node, its
operands are remapped with MDNodeMapper::mapDistinctNode and
MDNodeMapper::mapTopLevelUniquedNode until all nodes have been
mapped.
Sadly there's nothing observable I can test here; no real functionality
change, just a compile-time speedup from reduced malloc traffic.

ValueMapper: Eliminate cross-file co-recursion, NFC
Eliminate co-recursion of Mapper::mapValue through
ValueMaterializer::materializeInitFor, through a major redesign of the
ValueMapper.cpp interface.
- Expose a ValueMapper class that controls the entry points to the
mapping algorithms.
- Change IRLinker to use ValueMapper directly, rather than
llvm::RemapInstruction, llvm::MapValue, etc.
- Use (e.g.) ValueMapper::scheduleMapGlobalInit to add mapping work to
a worklist in ValueMapper instead of recursing.
There were two fairly major complications.
Firstly, IRLinker::linkAppendingVarProto incorporates an on-the-fly IR
ugprade that I had to split apart. Long-term, this upgrade should be
done in the bitcode reader (and we should only accept the "new" form),
but for now I've just made it work and added a FIXME. The hold-op is
that we need to deprecate C API that relies on this.
Secondly, IRLinker has special logic to correctly implement aliases with
comdats, and uses two ValueToValueMapTy instances and two
ValueMaterializers. I supported this by allowing clients to register an
alternate mapping context, whose MCID can be passed in when scheduling
new work.
While out of scope for this commit, it should now be straightforward to
remove recursion from Mapper::mapValue.

ARM: don't try to hoist constant RHS out of a division.
Divisions by a constant can be converted into multiplies which are usually
cheaper, but this isn't possible if the constant gets separated (particularly
in loops). Fix this by telling ConstantHoisting that the immediate in a DIV is
cheap.
I considered making the check generic, but neither AArch64 (strangely) nor x86
showed any benefit on the tests I had.
