[PATCH] D55823: [analyzer] Fix backward compatibility issue after D53280 'Emit an error for invalid -analyzer-config inputs'

[Artem Dergachev via Phabricator via llvm-commits]

NoQ added a comment.

George committed this as rC349863 <https://reviews.llvm.org/rC349863>. Before that happened, we kinda figured out how it works: `-analyzer-config` is not a flag, it's an argument of the `-Xclang` flag, so we should look for `-Xclang` and see what value does the argument have.

Now, there's also `-Xanalyzer`. But `-Xanalyzer` is automatically not consumed during compilation, so any `-analyzer-config` flags passed through it would be ignored during compilation.

However, `--analyze -Xanalyzer -analyzer-config ...` is now broken :/
