- This patch is the second (and hopefully final) part of providing HLASM syntax for inline asm statements for z/OS to LLVM (continuing on from https://reviews.llvm.org/D98276)
- This second part deals with providing label support
- As mentioned in https://reviews.llvm.org/D98276, if the first token is not a space we process the first token as a label, and the remaining tokens as a possible machine instruction
- To achieve this, a new `parseAsHLASMLabel` function is introduced. This function processes the first token, validates whether it is an "acceptable" label according to HLASM standards, and then emits it
- After handling and emitting the label, call the `parseAsMachineInstruction` instruction to process the remaining tokens as a machine instruction.
