Continuing with #3070. Just a dir and file rename (only prefix change is lexer_file_test). Everything in the lex dir should be marked as a move. Note, I think this closes #3070. There may still be further cleanup later, but the organizational changes suggested there are being completed. --------- Co-authored-by: Chandler Carruth <chandlerc@gmail.com>
