This switches fish to a "virtual" PWD, where it no longer uses getcwd to discover its PWD but instead synthesizes it based on normalizing cd against the $PWD variable. Both pwd and $PWD contain the virtual path. pwd is taught about -P to return the physical path, and -L the logical path (which is the default). Fixes #3350
