Good news, folks! Hagbard was kind enough to send an older build of OVMF he had lying around and suggested I try it. I did, and I am happy to report my VM boots very fast again! For safekeeping, I have committed it to my GitHub repository: https://github.com/jkoelndorfer/local-tools/blob/master/workstation/vfio/edk2.git-ovmf-x64-0-20150804.b1143.g8ca1489.noarch.rpm. I believe that when I did my initial VFIO setup, I used a package from the AUR which may have been just old enough to avoid the problem.
I may experiment some and see if any of the qemu parameters provided by Hristo make a difference with a current version of OVMF. For now, I'm happy my VM is booting quickly. Thanks very much for your help.
