This file fails to assemble with llvm-mc:

  $ cat x.s
  movq 18446744073709551615,%rbx
  $ as x.s
  $ gcc -c x.s
  $ clang -c x.s
  x.s:1:7: error: Invalid decimal number
  movq $18446744073709551615,%rbx
        ^
  x.s:1:7: error: unknown token in expression
  movq $18446744073709551615,%rbx
        ^

That number is the 64-bit unsigned representation of "-1", by the way.
