WIP as it requires: #1302

Fix LIT tests that are not compiled with assertions enabled but call
assert.

Aren't assertions enabled by default and should be explicitly disabled with NDEBUG?

@bader You are right and my PRs to replace assert with a different macro are not required. Great catch and removes unnecessary code changes/PRs.

I seemingly got confused due to working for too long with CMake and explicit CMAKE_BUILD_TYPE settings which for release builds set NDEBUG.

@bjoernknafla, do you want to proceed with these changes?

I need/want to rework this a bit - should I close and reopen it once ready or keep it open and marked as WIP?

I'm fine to keep it open.

I was confused by your previous comment:

WIP as it requires: #1302

#1302 is closed, so it was not clear to me whether you decided to abandon this PR or continue with this approach.

As I learned from you, assert won’t be compiled out without explicitly setting NDEBUG, so I closed the MR that introduced a CHECK macro to replace assert. This PR needs to be adapted accordingly.

I striked that old comment through now to prevent future confusion.

This PR is old and outdated and I won't be able to get back to it for a while. While the LIT tests could need another revisit to ensure that exceptions are not ignored I suggest to close this PR.

Thanks for the update.
