[Bug tree-optimization/59591] [4.9 Regression] ICE in vect_get_vec_def_for_stmt_copy, at tree-vect-stmts.c:156 for -march=core-avx2

Unfortunately, I don't have access to any CPUs with AVX2 right now, so can't test whether it works there properly.

--- Comment #3 from Jakub Jelinek jakub at gcc dot gnu.org ---
Slightly reduced fortran testcase for -O3 -mavx2:
subroutine foo (m, n, o, p, q, e, a, b, x, f)
integer, intent (in) :: n, o, p, q, m, f
integer, dimension (n:o) :: e, a, b
integer, dimension (n:o, p:q) :: x
integer :: j, i
do j = 1, m
do i = n, f
if (e(i) .eq. 0) then
a(i) = x(i, b(i))
endif
enddo
enddo
end subroutine foo
and C testcase for -O3 -mavx2 -fopenmp-simd:
int p[256], q[256], r[256], t[256];
void
foo (void)
{
int i;
#pragma omp simd safelen(64)
for (i = 0; i 256; i++)
if (r[i] 32)
t[i] = p[q[i] * 3L + 2L];
}

Still need to turn the testcase into runtime testcase and look at the other gather direction (the patch fixes the modifier = NARROW case, need to look at modifier = WIDEN case).
