[debuginfo-tests] r300467 - Revert "Revert "Add a test for __block variables + asan.""

[Vedant Kumar via llvm-commits]

Hey Adrian,

Could you share where the "not_asan" lit feature is defined? I'm running into some problems with it.

Specifically the code coverage bot defines "not_asan" (somehow.. not sure how yet!), even though it doesn't build the ASan runtime. This is causing the bot to break.
