  [ELF] Support -plugin-opt=stats-file=

This flag is added by clang::driver::tools::addLTOOptions() and was causing
errors for me when building the llvm-test-suite repository with LTO and
-DTEST_SUITE_COLLECT_STATS=ON. This replaces the --stats-file= option
added in 1c04b52b2594d403f739ed919ef420b1e47ae343 since the flag is only
used for LTO and should therefore be in the -plugin-opt= namespace.

Additionally, this commit fixes the `REQUIRES: asserts` that was added in
948d05324a150a5a24e93bad07c9090d5b8bd129: the feature was never defined in
the lld test suite so it effectively disabled the test.
