Rename some variables to match lowerShuffleAsRepeatedMaskAndLanePermute - prep work toward adding some equivalent sublane functionality.

The static analyzer is warning about potential null dereferences, but we should be able to use castAs<> directly and if not assert will fire for us.

Summary:
This patch makes the `SpacesInSquareBrackets` setting also apply to C++ lambdas with parameters.
Looking through the revision history, it appears support for only array brackets was added, and lambda brackets were ignored. Therefore, I am inclined to think it was simply an omission, rather than a deliberate choice.
See https://bugs.llvm.org/show_bug.cgi?id=17887 and https://reviews.llvm.org/D4944.

This looks like a defect in gcc-5 where it chooses a constexpr
constructor from the initializer-list that it considers to be explicit.
I've tried to reproduce but I can't install anything prior to gcc-6 easily
on my system, and that doesn't have the error. So this is speculative
pacification.

The motivation is to reuse the key value parsing logic here to
parse instance specific pass options within the context of MLIR.
The primary functionality exposed is the "," splitting for
arrays and the logic for properly handling duplicate definitions
of a single flag.

This is an omission in rL371441. Loads which happened to be unordered weren't being added to the PendingLoad set, and thus weren't be ordered w/respect to side effects which followed before the end of the block.
Included test case is how I spotted this. We had an atomic load being folded into a using instruction after a fence that load was supposed to be ordered with. I'm sure it showed up a bunch of other ways as well.
Spotted via manual inspecting of assembly differences in a corpus w/and w/o the new experimental mode. Finding this with testing would have been "unpleasant".

If you explicitly set LIBCXX_ENABLE_EXPERIMENTAL_LIBRARY to OFF, your
project will fail to configure because the cxx_experimental target
doesn't exist.
llvm-svn: 373809
Also, set those flags for the cxx_experimental target. Otherwise,
cxx_experimental doesn't build properly when neither the static nor
the shared library is compiled (yes, that is a weird setup).

Summary:
[libomptarget][nfc] Update remaining uint32 to use lanemask_t
Update a few functions in the API to use lanemask_t instead of i32. NFC for
nvptx. Also update the ActiveThreads type in DataSharingStateTy.
This removes a lot of #ifdef from the downsteam amdgcn implementation.

This reverts r371177 (git commit f879c68755)
It caused PR43566 by removing empty, address-taken MachineBasicBlocks.
Such blocks may have references from blockaddress or other operands, and
need more consideration to be removed.
See the PR for a test case to use when relanding.

Now that we do shell expansion on POSIX with the user's shel, this test
can potentially fail. This should ensure that we always use /bin/sh.

We do indeed already get it right in some cases, but only transitively,
with one-use restrictions. Since we only need to produce a single
comparison, it makes sense to match the pattern directly:

llvm-svn: 373802
Initially (D65380) i believed that if we have rightshift-trunc-rightshift,
we can't do any folding. But as it usually happens, i was wrong.
https://rise4fun.com/Alive/GEwhttps://rise4fun.com/Alive/gN2O
In https://bugs.llvm.org/show_bug.cgi?id=43564 we happen to have
this very sequence, of two right shifts separated by trunc.
And "just" so that happens, we apparently can fold the pattern
if the total shift amount is either 0, or it's equal to the bitwidth
of the innermost widest shift - i.e. if we are left with only the
original sign bit. Which is exactly what is wanted there.

The current version of the pretty printers are not python3 compatible,

In the past, lit used threads to run tests in parallel. Today we use
`multiprocessing.Pool`, which uses processes. Let's stay more abstract
and use "worker" everywhere.

Outlining from noreturn functions doesn't do the correct thing right now. The
outliner should respect that the caller is marked noreturn. In the event that
we have a noreturn function, and the outlined code is in tail position, the
outliner will not see that the outlined function should be tail called. As a
result, you end up with a regular call containing a return.
Fixing this requires that we check that all candidates live inside noreturn
functions. So, for the sake of correctness, don't outline from noreturn
functions right now.
Add machine-outliner-noreturn.mir to test this.

InstrEmitter's virtual register handling assumes that clones are emitted
after the cloned node. Make sure this assumption actually holds.
Fixes a "Node emitted out of order - early" assertion on the testcase.
This is probably a very rare case to actually hit in practice; even
without the explicit edge, the scheduler will usually end up scheduling
the nodes in the expected order due to other constraints.
