gcc9-pr88489.patch

Untested fix.  The problem was that the sd pattern had the same RTL as the pd
for 128-bit vectors, but behaved differently.

--- Comment #3 from Jakub Jelinek  ---
The test FAILs even at -O0 when built with -mavx512vl, when built e.g. with
-mavx512{bw,dq} it works fine.

--with-arch=native --with-cpu=native is equivalent to -march=skylake-avx512.
It used to pass before r265827.

Can't reproduce, the test passes for me just fine on i9-7960X.
