...s are then outlined. Outputs from a candidate are
returned via an output parameter, except for one output that is promoted to
a return value. During outlining the inputs into the candidate are
condensed by computing the equivalencies between the arguments at each
occurrence. An example of this is:
outlinedFn(1,6,1); -> outlinedFn(1,6);
outlinedFn(2,4,2); -> outlinedFn(2,4);
In the above, parameters 1 and 3 were found to be equivalent for all
occurrences, thus the amount of inputs was reduced to 2.

[RFC] Add IR level interprocedural outliner for code size.
Hi Andrey,
Questions and feedback are very much welcome.
- The explanation as to why the improvements can vary between the IR and
MIR outliner mainly boil down to the level of abstraction that each are
working at. The MIR level has very accurate heuristics and is effectively
the last post ISel target independent code gen pass. The IR outliner on the
other hand has more estimation in the cost
