This was caused by an overly general solution to #1100981.
https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/commit/fb68d9241f1338333cf5260136378e4a7ef43308
removed "Multi-Arch: same" from the packages that were not multiarch
co-installable (such as libmlir-19, which is not co-installable because
it contains /usr/lib/llvm-19/lib/libMLIR.so.19.1), but also removed that
annotation from the packages that *were* multiarch co-installable, such
as libllvm19 (which is co-installable, because it only contains
non-colliding paths like /usr/lib/x86_64-linux-gnu/libLLVM.so.19.1).
It would be useful if maintainers of packages that are involved in the
multiarch graphics stack, like LLVM and Mesa, could keep both the :amd64
and :i386 flavours of a package like mesa-vulkan-drivers installed on
their development machines (assuming they use x86, which I imagine that
most still do) - that would avoid this sort of thing getting uploaded
and regressing end-user systems.
