When run the command in the llvm-mc-assemble-fuzzer document,

  llvm-mc-fuzzer --triple=aarch64-linux-gnu --fuzzer-args -max_len=4

it triggers the following assertion:

  llvm-mc-assemble-fuzzer:
  llvm-project/llvm/lib/MC/MCTargetOptionsCommandFlags.cpp:38:
  bool llvm::mc::getRelaxAll(): Assertion `RelaxAllView &&
  "RegisterMCTargetOptionsFlags not created."' failed.

It is caused by no global RegisterMCTargetOptionsFlags object to initialize
the MC target options.
