Asked @sandersn and @weswigham and they didn't know why these are properties, but if I try to change undefined to a variable I can't build the compiler.

seems that this should be in utilities instead on the checker. nothing here is about the checker internal state, but rather how we mark symbols.

I think this one could use a second review. @sheetalkamat @weswigham @sandersn @rbuckton @mhegazy |

seems kinda weird that we add the symbol, then later on ask the checker if they were the ones we added.. i wounder if we can do something different here..

alas.. i could not come up with a better idea here myself. ignore my previous rant.

We could use SymbolOriginInfoMap with a union type { type: "this-type" } | { type: "export", ... }, would that be a good idea?

can we optimize this a bit instead of generating an extra object allocation on every entry.

do you not need replacement span eg. if refering to property x and you want to replace it with this.x ?

The default replacement span should already be the identifier itself. We only need to set replacementSpan if we are replacing something else, too, such as replacing .x with ["x"].
Fixes #21202
