Thanks for the revert.  Chandler suggested renaming to `llvm-examples`
and making `examples` an umbrella target that calls out to `llvm-` and
`clang-` (and potentially other) prefixes... maybe instead
`examples-all` would do the trick.  When I get back to this (not high
priority TBH) I'll try something along those lines.
