x86: Use dl-symbol-redir-ifunc.h on cpu-tunables
The dl-symbol-redir-ifunc.h redirects compiler-generated libcalls to arch-specific memory implementations to avoid ifunc calls where it is not yet possible. The memcmp-isa-default-impl.h aims to fix the same issue by calling the specific memset implementation directly. Using the memcmp symbol directly allows the compiler to inline the memset calls (especially because _dl_tunable_set_hwcaps uses constants values), generating better code. Checked on x86_64-linux-gnu.
