Ext mul's codegen assumes that all inputs are in registers, but the

mul is slightly complicated so we chose to restrict the inputs to be

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.

wasm-debug.{cc,h} and stores these maps on the DebugInfoImpl rather than
