Without this patch, when using lit's internal shell, if `not` on a lit RUN line calls `env`, `diff`, or any of the other in-process shell builtins that lit implements, lit accidentally searches for the latter as an external executable. What's worse is that works fine when a developer is testing on a platform where those executables are available and behave as expected, but it then breaks on other platforms. `not` seems useful for some builtins, such as `diff`, so this patch supports such uses. `not --crash` does not seem useful for builtins, so this patch diagnoses such uses. In all cases, this patch ensures shell builtins are found behind any sequence of `env` and `not` commands. `not` calling `env` calling an external command appears useful when the `env` and external command are part of a lit substitution, as in D65156. This patch supports that by looking through any sequence of `env` and `not` commands, building the environment from the `env`s, and storing the `not`s. The `not`s are then added back to the command line without the `env`s to execute externally. This avoids the need to replicate the `not` implementation, in particular the `--crash` option, in lit.
