Ideally we should just thread the address of the current address, unfortunately we cannot call X86MCCodeEmitter::encodeInstruction (X86MCCodeEmitter requires MCInstrInfo and MCContext) to get the length of the MCInst. MCInstPrinter::printInst has other callers (e.g llvm-mc -filetype=asm, llvm-mca) which set Address to 0. They leave MCInstPrinter::PrintBranchImmAsAddress as false and this change is a no-op for them. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D76580
