Collect compilation statistics #31
Description
We should collect statistics about compilation (behind a feature flag) about how much time each compilation step took, and some basic information about the compiled function (number of variables, basic blocks, instructions). Those statistics should be collected locally and sent to a database periodically.
This will help us understand where are the bottlenecks of the compilation process, and improve them.
This should be done after an explicit user consent, and should be removed entirely after we reach a semi-stable release.
