Compiler has different behavior on the test
gcc.dg/vect/no-tree-sra-bb-slp-pr50730.c with =E2=80=93mavx and =E2=80=93mn=
o-avx. With =E2=80=93mno-avx
routine get_vectype_for_scalar_type (scalar_type) at tree-vect-data-refs.c:=
3265
returns NULL for scalar_type =E2=80=9Cstruct A=E2=80=9D whereas with =E2=80=
=93mavx returns =E2=80=9Cvector(2)
__int128 unsigned=E2=80=9D.=20
The test is passed if constant 16 at line 6 of the test is replaced by 32 o=
r 64
(better 64 otherwise we will have the problem with avx2 in future).
