Consider recommending building with the Clang plugin #205
Description
mozilla-central includes an internal Clang plugin that adds static-analysis checks at build-time, to ensure things like proper use of smart pointers in C++: https://firefox-source-docs.mozilla.org/code-quality/static-analysis/existing.html#build-time-static-analysis
A list of checks that are performed by this plugin can be found here: https://searchfox.org/mozilla-central/rev/5a7e5e2e1fe04028fc77787084caf9b26ab74ce6/mfbt/Attributes.h#511
Both comm-central and try-comm-central build with this plugin, so I think we should recommend developers and contributors also enable it for their local builds to prevent bustages, by adding the following to their mozconfig file:
ac_add_options --enable-clang-plugin
