5096: Fix handling of whitespace when applying SSR within macro expansions. r=matklad a=davidlattimore
I originally did replacement by passing in the full file text. Then as some point I thought I could do without it. Turns out calling .text() on a node coming from a macro expansion isn't a great idea, especially when you then try and use ranges from the original source to cut that text. The test I added here actually panics without the rest of this change (sorry I didn't notice sooner).

5124: (Partially) fix handling of type params depending on type params r=matklad a=flodiebold
If the first type parameter gets inferred, that's still not handled correctly; it'll require some more refactoring: E.g. if we have `Thing<T, F=fn() -> T>` and then instantiate `Thing<_>`, that gets turned into `Thing<_, fn() -> _>` before the `_` is instantiated into a type variable -- so afterwards, we have two type variables without any connection to each other.

This test needs to be updated after every change (it contains line
number), which is annoying.
It also fails on windows due to \, so it's easier to remove it.
