Many Julia packages have nice code coverage views (e.g. [Codecov](https://app.codecov.io/gh/JuliaPlots/Plots.jl)). Is there a similar one for Base?

Wow. I feel silly for missing those. Thanks.

The line by line coverage seems to be broken ([e.g.](https://app.codecov.io/gh/julialang/julia/blob/master/sort.jl) says “There was a problem getting the source code from your provider. Unable to show line by line coverage.”). Am I missing something silly again?

[Confirmed](https://github.com/JuliaCI/julia-buildkite/issues/188): line by line overage is broken
