compiler: implement -stats option for running a _test.v file

Browse Source 
* 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.
