Near as I know there isn't any existing emulated SR-IOV device in QEMU.
But yes, an emulated SR-IOV would also be useful for testing purposes
for projects like OpenStack, without having the need for real hardware.

I'm far from an expert on this area, but just wanted to point out that
there's some existing support for SR-IOV in QEMU, added via:
[PATCH v6 0/4] pcie: Add support for Single Root I/O Virtualization --
https://lists.nongnu.org/archive/html/qemu-devel/2015-10/msg05155.html
Knut Omang (Cced) who added the above support also had some notes here
on how to implement an SR-IOV capable device.:
https://lists.nongnu.org/archive/html/qemu-devel/2015-10/msg05157.html
-- pcie: Add some SR/IOV API documentation in docs/pcie_sriov.txt
"Add a small intro + minimal documentation for how to implement
SR/IOV support for an emulated device.
