Chandler Carruth fe1ffb912d [LPM] Reinstate r271781 which reinstated r271652 to replace the
CALL_ONCE_... macro in the legacy pass manager with the new
llvm::call_once facility.

Nothing changed sicne the last attempt in r271781 which I reverted in
r271788. At least one of the failures I saw was spurious, and I want to
make sure the other failures are real before I work around them -- they
appeared to only effect ppc64le and ppc64be.

Original commit message of r271781:
----
[LPM] Reinstate r271652 to replace the CALL_ONCE_... macro in the legacy
pass manager with the new llvm::call_once facility.

This reverts commit r271657 and re-applies r271652 with a fix to
actually work with arguments. In the original version, we just ended up
directly calling std::call_once via ADL because of the std::once_flag
argument. The llvm::call_once never worked with arguments. Now,
llvm::call_once is a variadic template that perfectly forwards
everything. As a part of this it had to move to the header and we use
a generic functor rather than an explict function pointer. It would be
nice to use std::invoke here but we don't have it yet. That means
pointer to members won't work here, but that seems a tolerable
compromise.

I've also tested this by forcing the fallback path, so hopefully it
sticks this time.

Original commit message of r271652:
----
[LPM] Replace the CALL_ONCE_... macro in the legacy pass manager with
the new llvm::call_once facility.

This facility matches the standard APIs and when the platform supports
it actually directly uses the standard provided functionality. This is
both more efficient on some platforms and much more TSan friendly.

The only remaining user of the cas_flag and home-rolled atomics is the
fallback implementation of call_once. I have a patch that removes them
entirely, but it needs a Windows patch to land first.

This alone substantially cleans up the macros for the legacy pass
manager, and should subsume some of the work Mehdi was doing to clear
the path for TSan testing of ThinLTO, a really important step to have
reliable upstream testing of ThinLTO in all forms.

Simon Pilgrim fd2eda4f64 [X86][AVX2] Fix v16i16 SHL lowering (PR27730)
The AVX2 v16i16 shift lowering works by unpacking to 2 x v8i32, performing the shift and then truncating the result.

The unpacking is used to place the values in the upper 16-bits so that we can correctly sign-extend for SRA shifts. Unfortunately we weren't ensuring that the lower 16-bits were zero to ensure that SHL correctly shifts in zero bits.

Chandler Carruth fe9466fe2c [LPM] Revert r271781 which was a re-commit of r271652.
There appears to be a strange exception thrown and crash using call_once
on a PPC build bot, and a *really* weird windows link error for
GCMetadata.obj. Still need to investigate the cause of both problems.

[LPM] Reinstate r271652 to replace the CALL_ONCE_... macro in the legacy
pass manager with the new llvm::call_once facility.

Chandler Carruth b330dcab19 Ok, now I know why I kept getting confused and not making progress
fixing tis test. There are different configurations running, and they
have subtly different backtraces. I didn't notice that the configs
changed and so I kept occilating between the two.

Now I've looked at two different configs at the same time, and so this
should be much more likely to work.

Chandler Carruth 9ef4243824 Fix the test for printing the memory profile. This fuctionality is only
available along side the leak checking, so use the REQUIRES for that.

Also, use %run as other tests do when launching the built binary.

This fixes check-asan for me on Linux and looks like it should fix the
linux sanitizer bots as well.

Original commit message:

The only tests that need to be run on Linux are the ones that use C++
demangling. I'm assuming they will fail on Mac, since __cxa_demangle
there won't handle the non-double-underscore prefixed mangled names.

Chandler Carruth 0c30f89cca [llvm-profdata] Revert r271709 and the 3 subsequent commits - the code
and/or tests aren't working on Windows currently.

There seems to be some problem with quoting the file paths. I don't
understand the test structure here or the code well enough to try to
come up with a way to correctly handle paths with back slashes in them,
and this has caused the Windows builds to be failing for 7 hours now, so
I'm reverting the whole thing to bring them back to life. Sorry for the
disruption, but a couple of these were bug fixes anyways that can be
folded into a fresh commit.
