Currently, it is unclear if a test that is skipped is either:
- Unsupported because it will never run (macosx tests should not run on
Windows).
- Skipped because it's supposed to work but does not yet.
`@expectedFailure` is not always an option because a test might be
timing out and waiting 600s for it to fail is not acceptable.
This patch introduces 2 new decorators to differentiate those tests:
- `@requireX` meaning the tests require X to run (e.g `@requireDarwin`).
- `@requireNotX` meaning the tests requires anything but `X` to run (e.g
`@requireNotDarwin`).
In the tests results summary, this introduces a new category: `skipped`
tests:
- `@requireX` -> `UNSUPPORTED`
- `@skipIfX` -> `SKIPPED`
Here is how they can and cannot be stacked:
This will never run:
```py3
@requireDarwin
@requireWindows
def test():
...
```
This will not run on Linux, because `@requireWindows` is not satisfied.
```py3
@requireNotDarwin
@requireWindows
def test():
...
```
For "require Darwin or Windows", you need:
```py3
@requirePlatform(["darwin", "windows"])
def test():
...
```
For "require Darwin on ARM64 or Windows on ARM64", you need:
```py3
@requireARM64
@requirePlatform(["darwin", "windows"])
def test():
...
```
This patch also converts the tests in
`lldb/tests/API/{macosx,linux,windows}` to use these decorators. Patches
to convert the rest of the tests will follow.
