Description

The last switch to pts_to_mask (#81) made array operations a lot slower. For DPE I had to bump the z3rlimit to 20.

Research direction

Start by examining the pts_to_mask implementation and the change in issue #81, then reproduce the reported slowdown in array operations. Use the DPE case and its z3rlimit increase to identify the regression; done means restoring acceptable performance without requiring that workaround.
