Implements rust-lang/rfcs#2294 (tracking issue: #51114).

I probably should do a few more things before this can be merged:

  • Add tests (added basic tests, more advanced tests could be done in the future?)
  • Add lint for exhaustive if-let guard (comparable to normal if-let statements)
  • Fix clippy

However since this is a nightly feature maybe it's fine to land this and do those steps in follow-up PRs.

Thanks a lot @matthewjasper heart for helping me with lowering to MIR! Would you be interested in reviewing this?
r? @ghost for now
