Subject: checkout: Don't crash when switching away from an invalid branch.
X-Git-Tag: v1.6.1-rc1~73^2~2

checkout: Don't crash when switching away from an invalid branch.

When using alternates, it is possible for HEAD to end up pointing to
an invalid commit. git checkout should be able to recover from that
situation without crashing.
