[IRSim][IROutliner] Adding option to enable outlining from linkonceodr functions

[AndrewLitteken]

Summary

There are functions that the linker is able to automatically deduplicate, we do not outline from these functions by default. This allows for outlining from those functions.

Tests:

• llvm/test/Transforms/IROutliner/outlining-odr.ll

The comment seems to suggest that this ought to be set in the LTO pass pipeline, but that doesn't happen in this patch. Is this just for testing?

For now, it is for testing, and we do hope to put the pass in LTO eventually.
