Hi!

When looking at PR109596, I've noticed some comment typos.

Bootstrapped/regtested on x86_64-linux and i686-linux, committed to trunk as
obvious.

        * tree-ssa-loop-ch.cc (update_profile_after_ch): Fix comment typo:
        probabbility -> probability.
        (ch_base::copy_headers): Fix comment typo: itrations -> iterations.
