Whether assertions are enabled or not is orthogonal to the build type which could lead to surprising behavior for lldbassert. Previously, when doing a debug build with assertions disabled, lldbassert would become a NOOP, rather than printing an error like it does in a release build. By definining lldbassert in terms of NDEBUG, it behaves like a regular assert when assertions are enabled, and like a soft assert. Differential revision: https://reviews.llvm.org/D150639
