This is blocking development of my safe-ty branch which replaces the unsafety in rustc::middle::ty with lifetimes.
I would be thankful if this tiny fix made it into the next snapshot.

feat: Use oldest rustup rust-analyzer when toolchain override is present
Selects a rust-toolchain declared RA based on its date. The earliest (oldest) RA wins and becomes the one that the workspace uses as a whole.
In terms of precedence:
nightly > stable-with-version > stable
With stable-with-version, we invoke the RA with a `--version` arg and attempt to extract a date. Given the same date as a nightly, the nightly RA will win.
Fixesrust-lang#17663
