This PR adds a number of thus-far missing extended mnemonics to the assembler and disassembler for SystemZ. The following mnemonics have been added and are supported for the assembler and disassembler: - `NOP(R)?` - `LFI` - `RISBG(N)?Z` The following mnemonics have been added and are supported for the assembler only: - `JC(TH)?` - `LLG(F|H)I` - `NOT(G)?R`
