--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Part of it is because GCC did the conversion to vector unsigned long but then
does not detect the following two const_vect's are the same:
(const_vector:V16QI [
(const_int 99 [0x63]) repeated x16
])
(const_vector:V2DI [
(const_int 7161677110969590627 [0x6363636363636363])
repeated x2
])
(except for the different modes).
