#=== ERROR while installing mingw-w64-shims.0.2.0 =============================#
Cannot copy D:\a\alt-ergo\alt-ergo\_opam\.opam-switch\build\mingw-w64-shims.0.2.0\shim.exe to D:\a\alt-ergo\alt-ergo\_opam\bin\x86_64-w64-mingw32-gcc.exe (C:\hostedtoolcache\windows\opam\2.2.1\x86_64\opam.exe: "open" failed on D:\a\alt-ergo\alt-ergo\_opam\bin\x86_64-w64-mingw32-gcc.exe: Permission denied).
Since #1185, when substitutions change the domain of a variable, we no longer trigger propagations, which means that we can end up in a state where the bitlist and interval domains are not consistent (i.e. running [constrain_bitlist_from_interval] or [constrain_interval_from_bitlist] would shrink some domains).
This was initially part of #1185 but was accidentally removed as part of a simplification pass during review. Add it back.
