llvm-mirror/lib/MC/MCDisassembler/MCDisassembler.cpp
Fangrui Song 3a9f350cbb [Disassembler] Delete the VStream parameter of MCDisassembler::getInstruction()
The argument is llvm::null() everywhere except llvm::errs() in
llvm-objdump in -DLLVM_ENABLE_ASSERTIONS=On builds. It is used by no
target but X86 in -DLLVM_ENABLE_ASSERTIONS=On builds.

If we ever have the needs to add verbose log to disassemblers, we can
record log with a member function, instead of passing it around as an
argument.
