Since rustc doesn't do the assembly parsing itself, it is unable to detect when inline assembly ends with an instruction prefix, which doesn't make sense since it would apply to instructions from the compiler. This fixes rust-lang#82314 by mentioning that x86 instruction prefixes must not be used in inline assembly.
Inspired by rust-lang#90521 , and by the various `must_use` PRs; in all of those cases, the submitter of the PR could know that `relnotes` applied, but couldn't apply it themselves.
People should be able to help triage by observing that a change needs an FCP before we can apply it.

Add note about x86 instruction prefixes in asm! to unstable book Since rustc doesn't do the assembly parsing itself, it is unable to detect when inline assembly ends with an instruction prefix, which doesn't make sense since it would apply to instructions from the compiler. This fixes rust-lang#82314 by mentioning that x86 instruction prefixes must not be used in inline assembly. AFAICT x86 is the only instruction set with instruction prefixes.
…oshtriplett Clean up some `-Z unstable-options` in tests. Several of these tests were for features that have been stabilized, or otherwise don't need `-Z unstable-options`.

…r=Mark-Simulacrum rustbot allow labels `relnotes` was inspired by rust-lang#90521 , and by the various `must_use` PRs; in all of those cases, the submitter of the PR could know that `relnotes` applied, but couldn't apply it themselves. For `needs-fcp`, I think people should be able to help triage by observing that a change needs an FCP before we can apply it.
