I actually couldn't find any other places this could happen today (we seem to check for non-emptiness of compile commands most of the time). But I hadn't look into clang, apparently `createInvocationFromCommandLine` also assumes that.
Adding an assert and pushing the check to callers, as in theory they should probably check for it long before since many tools perform some sort of command line mangling. LMK if the check should reside in the callee instead.
