don't use label starting with 1

Starting with the latest nightly, this results in an error:

error: avoid using labels containing only the digits `0` and `1` in inline assembly
  --> src/instructions/segmentation.rs:81:18
   |
81 |                 "1:",
   |                  ^ use a different label that doesn't start with `0` or `1`
   |
   = note: an LLVM bug makes these labels ambiguous with a binary literal number
   = note: `#[deny(binary_asm_labels)]` on by default
