the inliner cycle, the LLVM inliner step-by-step tries to inline functions, runs
canonicalization passes to exploit newly exposed simplification opportunities,
and then tries to inline the further simplified functions. Some simple loop

Polly can conceptually be run at three different positions in the pass pipeline: an early optimizer before the standard LLVM pass pipeline, as a later
optimizer as part of the target specialization sequence, and theoretically also
with the loop optimizations in the inliner cycle. We only discuss the first two
options, as running Polly in the inline loop, is likely to disturb the inliner
