* Draft implementation of `v -stats file_test.v` . * compiler: call stuff in vlib/benchmark/tests/always_imported.v, when doing `v -stats file_test.v` * Nicer looking output from 'v -stats file_test.v' . * Tweak colors and layout of -stats file_test.v . * Fix a hardcoded path in compiler/main.v . * Show colorized OK/FAIL for the examples in 'v test v' too. * Add some comments about the purpose of the methods inside vlib/benchmark/tests/always_imported.v . * when fails are 0, do not colorize their number at all.
