Performance regression in #32582

[amcasey]

The extra work done in #32582 is valuable, but maybe it doesn't need to be so expensive.

Setup:

1. Clone https://github.com/amcasey/material-ui.git
2. Check out Benchmark
3. yarn to restore packages
4. yarn typescript to prebuild and run some TS tests

Repro

1. tsc -p docs

On a random Mac Mini:

• 10-run avg on d00056f: 28,858ms
• 10-run avg on 480b739: 31,001ms (7% slower)

Note: to build old TS commits, you probably need to change const { default: chalk } to const chalk in scripts/build/utils.js.

@ahejlsberg You seem to be on a roll with clawing back these perf regressions, so I thought I'd bring this one other large regression to your attention. 😉
