The VG_(get_fnname_kind) function detects some special "below main" function names. Specifically __libc_start_main and generic_start_main both of which are used to call the actual main () function from the application. We already recognized one variant, generic_start_main.isra.0, but only for powerpc. Recognize all possibly specialed optimized variants gcc can produce by simply checking for the function name with dot as prefix. This fixes the memcheck/tests/supp_unknown.vgtest and massif/tests/deep-D.vgtest with gcc 11. We can now also get rid of the special cases in massif/tests/deep-D.post.exp-ppc64 and memcheck/tests/supp_unknown.supp. https://bugs.kde.org/show_bug.cgi?id=430158
