Extensible records: error message with incorrect LoC

[cknitt]

type t = {x: int, y: string}

type t2 = {x: string, y: float}

type t3 = {...t, ...t2}

(correctly) gives the error message "Two labels are named x".

But the location of the error message is wrong/confusing, as it points to t2, not t3:

@cristianoc can I add tests for errors somehow?

Yes though it's a bit repetitive to do that.
Try git log jscomp/build_tests/super_errors for the last ones added and jscomp/build_tests/super_errors/README.md for instructions on how to update the expectation files.
One needs a different file for each test, unlike other kinds of tests.
Would be nice to get around that limitation but there's no way as things are set up at the moment.\
