> What other tests should we use for compile-time performance measurement?
> What tests should we use for code quality?
For both of these, the Linux kernel is a good choice. You can
test code quality by running a web benchmark with Tux2 over
loopback with the files in a ramfs (memory-based) filesystem.
> Should -fstrict-aliasing be enabled?
Yes, at -O3 level and above. The forced inlining at -O3 is junk.
> Should we use flags higher than -O2 -g when bootstrapping?
Yes, to get -fstrict-aliasing at -O3. Use -O9 in fact.

With automated testing, you should be able to add every
platform you can find.
