We should probably check how much time taken is by the analyzer.
My goal is that the analyzer should "merely" double the compile time.
Perhaps express time taken by analyzer as a multiple of time taken by the rest of the compile; group files by the multiple?
Probably should add absolute and comparison report scripts for this
I've filed https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109361 with GCC to track adding profiling information to the SARIF files
