Update the binary_asm_label documentation

Disable a test that now only passes on x86 and make the link point to
the new (open) LLVM bug.

-    /// A [LLVM bug] causes this code to fail to compile because it interprets the `0b` as a binary
-    /// literal instead of a reference to the previous local label `0`. Note that even though the
-    /// bug is marked as fixed, it only fixes a specific usage of intel syntax within standalone
-    /// files, not inline assembly. To work around this bug, don't use labels that could be
-    /// confused with a binary literal.
