I think we can close this. I updated VS and followed the repro instructions
from the MSVC bug:
https://developercommunity.visualstudio.com/t/msvc-copies-overaligned-non-trivially-copyable-par/1179643
... and things seem to work now at this version:

$ cl -GS- t.cpp  && ./t.exe
Microsoft (R) C/C++ Optimizing Compiler Version 19.28.29914 for x86

t.cpp
Microsoft (R) Incremental Linker Version 14.28.29914.0
Copyright (C) Microsoft Corporation.  All rights reserved.

/out:t.exe
t.obj
w.self 0041F908


The Visual Studio version is 16.9.4. I think this was always just an MSVC bug
and they fixed it, although they neglected to specify which compiler version
received the fix.

Separately, now I want to try an x86 msvc debug build to see if I can repro
these ICEs. :)
