[llvm] [LV][NFC] Remove "REQUIRES: asserts" line from some tests (PR #191795)

[David Sherwood via llvm-commits]

https://github.com/david-arm created https://github.com/llvm/llvm-project/pull/191795

Several tests seemed to require asserts despite not testing any debug output so I have removed the line.

Subject: [PATCH] [LV][NFC] Remove "REQUIRES: asserts" line from some tests

Several tests seemed to require asserts despite not testing any
debug output so I have removed the line.
