[NFC] Switch a number of DenseMaps to SmallDenseMaps for speedup (#109417)
If we use SmallDenseMaps instead of DenseMaps at these locations,
we get a substantial speedup because there's less spurious malloc
traffic. Discovered by instrumenting DenseMap with some accounting
code, then selecting sites where we'll get the most bang for our buck.
