[sanitizer] [msan] Fix origin store of array types
This patch fixes the memory sanitizer origin store instrumentation for
array types. This can be triggered by cases where frontend lowers
function return to array type instead of aggregation.
For instance, the C code:
--
struct mypair {
int64_t x;
int y;
};
mypair my_make_pair(int64_t x, int y) {
mypair p;
p.x = x;
p.y = y;
return p;
}
int foo (int p)
{
mypair z = my_make_pair(p, 0);
return z.y + z.x;
}
--
It will be lowered with target set to aarch64-linux and -O0 to:
--
[...]
define i32 @_Z3fooi(i32 %p) #0 {
[...]
%call = call [2 x i64] @_Z12my_make_pairxi(i64 %conv, i32 0)
%1 = bitcast %struct.mypair* %z to [2 x i64]*
store [2 x i64] %call, [2 x i64]* %1, align 8
[...]
--
The origin store will emit a 'icmp' to test each store value again the
TLS origin array. However since 'icmp' does not support ArrayType the
memory instrumentation phase will bail out with an error.
This patch change it by using the same strategy used for struct type on
array.
It fixes the 'test/msan/insertvalue_origin.cc' for aarch64 (the -O0 case).

[Orc] Add support for remote JITing to the ORC API.
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.

[ADT] Add an abstraction for embedding an integer within a pointer-like
type.
This makes it easy and safe to use a set of flags as one elmenet of
a tagged union with pointers. There is quite a bit of code that has
historically done this by casting arbitrary integers to "pointers" and
assuming that this was safe and reliable. It is neither, and has started
to rear its head by triggering safety asserts in various abstractions
like PointerLikeTypeTraits when the integers chosen are invariably poor
choices for *some* platform and *some* situation. Not to mention the
(hopefully unlikely) prospect of one of these integers actually getting
allocated!
With this, it will be straightforward to build type safe abstractions
like this without being error prone. The abstraction itself is also
remarkably simple thanks to the implicit conversion.
This use case and pattern was also independently created by the folks
working on Swift, and they're going to incrementally add any missing
functionality they find.

[ADT] Add a sum type abstraction for pointer-like types.
This is a much more general and powerful form of PointerUnion. It
provides a reasonably complete sum type (from type theory) for
pointer-like types. It has several significant advantages over the
existing PointerUnion infrastructure:
1) It allows more than two pointer types to participate without awkward
nesting structures.
2) It directly exposes the tag so that it is convenient to write
switches over the possible members.
3) It can re-use the same type for multiple tag values, something that
has been worked around by either abusing PointerIntPair or defining
nonce types and doing unsafe pointer casting.
4) It supports customization of the PointerLikeTypeTraits used for
specific member types. This means it could (in theory) be used even
with types that are over-aligned on allocation to expose larger
numbers of bits to the tag.
All in all, I think it is at least complimentary to the existing
infrastructure, and a strict improvement for some use cases.

[JumpThreading] Don't forget to report that the IR changed
JumpThreading's runOnFunction is supposed to return true if it made any
changes. JumpThreading has a call to removeUnreachableBlocks which may
result in changes to the IR but runOnFunction didn't appropriate account
for this possibility, leading to badness.
While we are here, make sure to call LazyValueInfo::eraseBlock in
removeUnreachableBlocks; JumpThreading preserves LVI.
This fixes PR26096.

[WinEH] Fix catchpad pred verification
Summary:
The code was simply ensuring that the catchpad's pred is its catchswitch,
which was letting cases slip through where the flow edge was the unwind
edge of the catchswitch rather than one of its catch clauses.

[WinEH] Disallow cyclic unwinds
Summary:
Funclet-based EH personalities/tables likely can't handle these, and they
can't be generated at source, so make them officially illegal in IR as
well.
