  Log Message:
  -----------
  Revert "[Inliner] Propagate callee argument memory access attributes before inlining"

This exposes a miscompile reported in
https://github.com/llvm/llvm-project/issues/95152.

Whether the new inference or MemCpyOpt is at fault depends on
the precise semantics of writeonly attributes. Revert the patch
while this is being pinned down.

This reverts commit 285dbed147e243f416b003e150d67ffb0922ff16.
