Those benchmarks are built with bootstrap KGP and snapshot compiler.
Currently the former is K1, while the latter is K2. As a result, the
build fails because K2 compiler needs -Xfragment-sources argument,
while K1 uses -Xcommon-sources. So KGP passes the latter, while the
compiler expects the former.
Fix this by forcing KGP to use K2 for benchmarks in performance/
This can be reverted once bootstrap is updated to 2.0.0.
I was forced to manually do update the following files, because otherwise
they would be ignored according .gitignore settings. Probably they
should be deleted from repo.
