[committed] ipa-devirt: make qsort helpers static

[Alexander Monakov]

Hi,

noticed this when checking a qsort patch, applying as obvious.

In the C days, -Wmissing-prototypes would have caught this, but C++ needs a
different warning (-Wmissing-declarations), so we get inevitable bitrot :/

        * ipa-devirt.c (type_warning_cmp): Make static.
        (decl_warning_cmp): Ditto.
