git_llvm_rev: handle merge commits more gracefully
llvm grew a relatively large merge commit recently, which broke this
script noticeably.
There's analysis of why this happened in the bug. tl;dr is that
`rev-parse ${sha}~${N}` and `rev-list --count` don't do the same thing
without extra flags.
BUG=chromium:1041016
TEST=Unit tests. A few random runs in my LLVM tree.
