    validate: enable -DDEBUG in stage 1 by default
    
    Since the whole point of validation is to test the compiler, assertions
    should be enabled at least for some part of the build. Previously
    assertions were only enabled (1) in stage 2 compiler (2) when "slow"
    setting is used. With this patch we enable assertions in stage 1
    compiler in all settings, to test them on (1) the compiler itself (2)
    the libraries, even with the "fast" setting.
    
    This will make "fast" setting slower, but the difference should be quite
    modest - I didn't realize a significant difference in validation times.
