It should be possible to use the github APIs to post some of the errors from our builds directly as PR comments, for example:

• The code formatting errors have line numbers and can be flagged as comments in the PR.
• Any clang-tidy errors (in a future clang-tidy build) have line numbers and can be flagged as comments in the PR.
• The errors from the sanitizers often have line numbers and could be posted to the review too.
