A subtlety here:

Suggested change
if num_special >= num_affine
if num_special > num_affine

Here's the reasoning behind: when num_special == num_affine, according to #40, all special operations support affinemap, hence they can be unrolled using unroll_applyaffine

Tests and benchmarks are required to verify this change. If luckily we can get a performance boost here. At present, I can't make any promise.

Results

A ratio greater than 1.0 denotes a possible regression (marked with ❌), while a ratio less
than 1.0 denotes a possible improvement (marked with ✅). Only significant results - results
that indicate possible regressions or improvements - are shown below (thus, an empty table means that all
benchmark results remained invariant between builds).

Results

Below is a table of this job's results, obtained by running the benchmarks.
The values listed in the ID column have the structure [parent_group, child_group, ..., key], and can be used to
index into the BaseBenchmarks suite to retrieve the corresponding benchmarks.
The percentages accompanying time and memory values in the below table are noise tolerances. The "true"
time/memory value for a given benchmark is expected to fall within this percentage of the reported value.
An empty cell means that the value was zero.
