8l: step toward native client. · 4a4ec238

  - ELF header bits and addresses
  - do not let instructions span 32-byte boundary
  - align CALLs so return is to 32-byte boundary
  - align indirect jump targets to 32-byte boundary

  - replace indirect jump, indirect call, and ret with
    nacl-approved instruction sequences
