checkout: optimize "git checkout -b <new_branch>"
Skip merging the commit, updating the index and working directory if and
only if we are creating a new branch via "git checkout -b <new_branch>."
Any other checkout options will still go through the former code path.
If sparse_checkout is on, require the user to manually opt in to this
optimzed behavior by setting the config setting checkout.optimizeNewBranch
to true as we will no longer update the skip-worktree bit in the index, nor
add/remove files in the working directory to reflect the current sparse
checkout settings.
For comparison, running "git checkout -b <new_branch>" on a large repo takes:
14.6 seconds - without this patch
0.3 seconds - with this patch
