[Attributor][NFC] Performance improvements (#122923)
` forallInterferingAccesses` is a hotspot and for large modules these
changes make a measurable improvement in compilation time.
For LTO kernel compilation of 519.clvleaf (SPEChpc 2021) I measured the
following:
```
| Measured times (s) | Average | speedup
--------------------+------------------------+---------+---------
Baseline | 33.268 33.332 33.275 | 33.292 | 0%
Cache "kernel" | 30.543 30.339 30.607 | 30.496 | 9.2%
templatize callback | 30.981 30.97 30.964 | 30.972 | 7.5%
Both changes | 29.284 29.201 29.053 | 29.179 | 14.1%
