Rollup merge of #90533 - Smittyvb:patch-1, r=joshtriplett
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 #82314 by mentioning that x86 instruction prefixes must not be used in inline assembly. AFAICT x86 is the only instruction set with instruction prefixes.
