Log:
[utils] Generate html reports with the code coverage utility script
Instead of extracting raw coverage mappings into an artifact directory,
actually generate useful html reports for a given list of binaries with
symbol demangling turned on.
No tests, but this is actively being used to drive the (still nascent)
coverage bot.
