I dont know enough to modify the code in a sane way to get linalg.map outputs (when appropriate) so if anyone has any ideas, i would love to hear. I dont think it's important enough to go crazy with, but would be nice.

After a chat with @rengolin [here](https://discourse.llvm.org/t/rfc-extend-linalg-elemwise-named-ops-semantics/83927/13) , in particular

In this case, a fusion of two `elementwise` operations would yield a `map`

it's probably important enough to warrant discussion
