Resolves #141664

This changes rustdoc's --emit to allow only one instance of each type, regardless of the actual data that --emit carries. This matches rustc's --emit behavior.

As of the writing, only dep-info emit type carries extra data.

It should have the same behavior as rustc, which the last wins.

It does work, however the set of modified files also include tests/run-make/, for which I am an (equal precedence) eligible reviewer:

"/tests/run-make" = ["@jieyouxu"]

Out of interest, is their a similar test for rustc itself?

I didn't see any test specifically for the --emit precedence.

fix(rustdoc): match rustc `--emit` precedence

Resolves #141664

This changes rustdoc's `--emit` to allow only one instance of each type, regardless of the actual data that `--emit` carries. This matches rustc's `--emit` behavior.

As of the writing, only `dep-info` emit type carries extra data.
