Ext mul's codegen assumes that all inputs are in registers, but the instruction-selector wasn't the correct constraints. The codegen for ext mul is slightly complicated so we chose to restrict the inputs to be registers rather than changing codegen.

When merging a bundle with itself, we should consider the merge a success even though we do not merge anything. The result is used to determine whether the backward spilling heuristic might introduce a stack to stack move. For this purpose, it only matters whether the phi and its input end up in the same bundle.
