--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fre is able to handle it for constants:
Value numbering stmt = __builtin_memset (&x, 255, 16);
Setting value number of .MEM_3 to .MEM_3 (changed)
Value numbering stmt = x.1_7 = x;
Setting value number of x.1_7 to { -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1,
-1, -1, -1, -1, -1 } (changed)
