[InstSimplify] Adjust context instruction when threading phi (PR61312)

When threading operations over phis, we need to adjust the context
instruction to the terminator of the incoming block. This was
handled when threading icmps, but not when threading binops.

Fixes https://github.com/llvm/llvm-project/issues/61312.
