Take #2. Don't piggyback on the existing config.build_mode. Instead, define a new lit feature for each build feature we need (currently just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define this feature within test/lit.site.cfg. This doesn't require any lit harness changes and should be more robust across build systems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133664 91177308-0d34-0410-b5e6-96231b3b80d8
