Rollup merge of #98998 - workingjubilee:naked-means-no-clothes-enforcement-technology, r=Amanieu

Remove branch target prologues from `#[naked] fn` This patch hacks around rust-lang/rust#98768 for now via injecting appropriate attributes into the LLVMIR we emit for naked functions. I intend to pursue this upstream so that these attributes can be removed in general, but it's slow going wading through C++ for me.
