* Move compiler/ under vlib/compiler/ .
* Add a minimal compiler/main.v driver program.
* Cleanup compiler/main.v .
* Make most compiler tests pass again.
* Apply the fix by @joe-conigliaro , so that the rest of the compiler tests are fixed too.
* Thanks to @avitkauskas, now the vlib/vcompiler/tests/str_gen_test.v test does not need to be special cased anymore.
* Reapply @joe-conigliaro fix for vgen.
* compiler: -g and -debug should always add -g at least in the C compiler by default.
* Set first the C backend debug_options, so that the optimization_options can override them later.
* Implement cleaner named is_debug, is_vlines, is_keep_c and is_cache options (i.e. -g/-cg, -keep_c, -cache v flags).
* Check and reset file/line numbers in the generated main program, only if v.pref.is_vlines is true.
* Add source line numbers to backtraces on linux.
* Fix -g (broken after token caching).
* reset the #line directives after all the v code is compiled
* cleanup p.cgen.line setting inside p.next() .
* Support windows filepaths like "C:\Users\travis\build\vlang\v\v.exe.tmp.c" inside generated #line directives.
* Try to diagnose better windows-gcc failing.
* Revert "Try to diagnose better windows-gcc failing."
* implement and use cescaped_path/1 .
* Use cescaped_path/1 consistently throughout compiler/ .
* 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.
