    Adjust LLVM_ENABLE_ABI_BREAKING_CHECKS depending on NDEBUG
    
    When assertions are disabled, the upstream build system disables
    LLVM_ENABLE_ABI_BREAKING_CHECKS by default. Though the upstream build
    system allows it to be force-enabled, it looks like that is not a
    well-tested build-time configuration.
    
    Therefore, always disable LLVM_ENABLE_ABI_BREAKING_CHECKS when
    assertions are disabled, which will also save some more runtime cost
    when people use WITHOUT_LLVM_ASSERTIONS.
