Request Commit Access For fahadnayyar

I work in the clang compiler team at Apple. 
I have made some commits in the upstream llvm-project repository in the past via Phabricator. I plan to make some more patches to the clang frontend in next few months. So I wanted to get commit access to the main branch of llvm-project via GitHub so that I can submit PRs, get approvals and merge my changes into the main branch of LLVM.
