* 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.
