[RFC] Usage of NDEBUG as a guard for non-assert debug code

[RFC] Usage of NDEBUG as a guard for non-assert debug code
Hi all, During discussions about assertions in the Flang project, we noticed that there are a lot of cases in LLVM that #ifndef NDEBUG is used as a guard for non-assert code that we want enabled in debug builds. This works fine on its own, however it affects the behaviour of LLVM_ENABLE_ASSERTIONS; since NDEBUG controls whether assertions are enabled or not, a lot of debug code gets enabled in
