fix compilation errors with latest llvm trunk (iovisor#2575)

llvm commit https://reviews.llvm.org/D66795
changed the signature of function createMCAsmInfo().
  -  MCAsmInfo *createMCAsmInfo(const MCRegisterInfo &MRI,
  -                             StringRef TheTriple) const {
  +  MCAsmInfo *createMCAsmInfo(const MCRegisterInfo &MRI, StringRef TheTriple,
  +                             const MCTargetOptions &Options) const {

Did similar adjustment in bcc to ensure compilation success.
