Swift Compiler flag "-w -Xanalyzer -analyzer-disable-all-checks" now fails the build
Which area are you seeing an issue with?
Swift Compiler
What type of feedback are you reporting?
Incorrect/Unexpected Behavior
Description
Please describe the issue:
In Xcode 11 Beta 4 adding compiler flag of "-w -Xanalyzer -analyzer-disable-all-checks" to a .swift source file causes compilation to fail with:

```
<unknown>:0: error: unknown argument: '-w'
<unknown>:0: error: unknown argument: '-Xanalyzer'
<unknown>:0: error: unknown argument: '-analyzer-disable-all-ch
```

This was not the case in Xcode 11 Beta 3 or Xcode 10 (any version)

I am not sure if this is intended or not so perhaps this is working correctly, can someone at Apple confirm?

Please list the steps you took to reproduce the issue:
Open the attached sample project and try to build it.
What did you expect to happen?
Compilation to be successful.
What actually happened?
Build failed.
