We only run LLDB 1500 in CI. Any test with a min-lldb-version above that
is currently ignored. It's not clear any of these tests actually work
with that LLDB version, and they definitely don't work on LLDB ~2100.
So, ignore them until we fix debuginfo testing.
So that when we later add support for revisions we can use the same
syntax for revisions as elsewhere.
This also prevents people from making typos for commands since
`src/tools/compiletest/src/directives/directive_names.rs` will catch such
typos now.
Note that we one FIXME for a non-trivial change for later:
```
// FIXME(148097): Change `// cdb-checksimple_closure` to `//@ cdb-check:simple_closure`
```
