When two identifiers follow eachother it could be two instruction mnemonics or one instruction mnemonic and one operand. To fix this TOKEN_NEWLINE has been reintroduced as a semantic token. The grammar has been changed to allow empty statements and every instruction and directive has to end in a newline. Labels do not have to end in a newline. In addition to updating the grammar, the implementation of tokenlist, ast and parser has been updated to reflect these changes.
