* 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.
* compiler: extract and cleanup error handling functionality into its own file compiler/compile_errors.v
* compiler: implement p.error_with_token_index and p.warn_with_token_index and use them. Fix tests.
