the old debug_assert always ran and tested the expression, which slows down release builds. wrapping them in #ifndef NDEBUG is clumsy. the new ASSERT behaves like assert and ENSURE like the old debug_assert. Let's change any time-critical but not-super-important ENSURE to ASSERT to speed up release builds. (already done in bits.h and unique_range.h) This was SVN commit r9362.
