5; This is a build test, that means it will be assembled, disassembled,
6; then the disassembly output will be assembled and the new binary will

25; The disassembler doesn't do imm32 right for 64-bit stuff, so disable it for now.

28; The cmpxchg16b/8b stuff isn't handled correctly in 64-bit mode. In the 8b case
29; it could be both yasm and the vbox disassembler. Have to check docs/gas/nasm.
