Hi,
For avx512f_scattersi, mask operand only affect set src, we need to
refine the pattern to let gcc know mask register also affect the dest.
So we put mask operand into UNSPEC_VSIBADDR.
Bootstrapped and regression tested on x86_64-linux-gnu{-m32,-m64}.
Ok for master?

Hi,
For avx512f_scattersi, mask operand only affect set src, we
need to refine the pattern to let gcc know mask register also affect the dest.
So we put mask operand into UNSPEC_VSIBADDR.
