[PATCH] D105169: [Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default

[Juneyoung Lee via Phabricator via cfe-commits]

aqjune added a comment.

I can see that `@ff_seek_frame_binary` is the only affected function.
It introduces `llvm.assume` as well as `!nonnull` at a few places and folds null pointer checks.
Still investigating..
