[PATCH] D82317: [Clang/Test]: Update tests where `noundef` attribute is necessary

[Gui Andrade via Phabricator via cfe-commits]

guiand added a comment.

After discussing with @eugenis, for the meantime it might be best to do the following:

- Change the masking attribute to be `-fdisable-noundef-analysis` (name notwithstanding), and have it completely turn off all `noundef`s
- Change the llvm-lit configuration to use the new codegen flag for all the tests by default
- Have `noundef` emitted in the frontend by default (when the codegen flag isn't present)
