Description

Problem*

Resolves

Summary*

I noticed that when we're unrolling loops we run 2 mem2reg passes and a simplify_cfg on all functions in the program after every failure. This means that we'll end up doing a lot of redundant work on all the other functions in the program as long as there's a single function which is still having loops unrolled.

This PR changes how we do loop unrolling so that we unroll a single function to completion before we start unrolling the next. This also opens up the opportunity to parallelize this work in future.

Additional Context
