chore: Add microbenchmarks for all expressions

[andygrove]

Which issue does this PR close?

Closes #2955

I will mark as ready for review after #2964, #2979, and #2980 are merged.

Rationale for this change

Add remaining benchmarks to cover all expressions. I can split these out into smaller PRs after the holidays if needed ... or we could just merge as is and then follow up with smaller PRs for any improvements that anyone wants. This PR gives us instant coverage of all expressions, which is helpful in prioritizing optimization efforts.
