Rollup merge of #129605 - jieyouxu:needs-llvm-components, r=Mark-Simulacrum

Add missing `needs-llvm-components` directives for run-make tests that need target-specific codegen

Without suitable `needs-llvm-components` directives, some run-make tests exercising target-specific codegen can fail if the LLVM used is built without the necessary components. Currently, the list is:

```
tests\run-make\print-target-list
tests\run-make\print-to-output
tests\run-make\print-cfg
tests\run-make\target-without-atomic-cas
```

This PR also skips tidy checks for revisions and `needs-llvm-components` for run-make tests since revisions are not supported.

Fixes #129390.
Fixes #127895.

cc ``@petrochenkov`` who noticed this, thanks! Would be great if you could confirm that this fixes the test errors for you locally.
