e72fe25224 compiler: more precise 'declared and not used' error positioning 
* 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.

* tools/performance_compare: add a 'Source lines in compiler/' line

* MSVC does not have STDOUT_FILENO nor STDERR_FILENO ...

8b8cd13929 parser: add some infrastructure for more specific errors 
* compiler: change s.line_nr in just one place, so that s.last_nl_pos will be updated in tandem too.

* Cleanup spurious spaces.

* Store ScannerPos info inside the cached tokens.

Use the stored information when errors are encountered.

* Fix #2079 ( cannot use type...in assignment ).

* do not store scannerpos per each token, instead rescan the source once on error to get the position.

* compiler: implement highlighting for errors. Use only line/col info stored in the cached tokens.

* fixing building on windows

* Split can_show_color to _nix and _win files.

a4cbe78d97 compiler: streamline main function handling 
* compiler: streamline C main function generation

* fix most tests

* compiler: fix for 'go update()' in graph.v . More precise parser error messages.

* Fix temporarily examples/hot_reload/message.v by using os inside it (os.clear).

* Make graph.v easier to quickly modify by defining y outside the loop.

* Fix failure of /v/nv/compiler/tests/defer_test.v when run with 'v -g' (#line directive was not on its own line, but right after } ).

* Do not pass the os.args to tests, even if the tests import os (they are more stable when run in a controlled environment).

* fix declared and not used in the js backend.

* fix js main => main__main too.
