Auto merge of rust-lang#92816 - tmiasko:rm-llvm-asm, r=Amanieu

Remove deprecated LLVM-style inline assembly The `llvm_asm!` was deprecated back in rust-lang#87590 1.56.0, with intention to remove it once `asm!` was stabilized, which already happened in rust-lang#91728 1.59.0. Now it is time to remove `llvm_asm!` to avoid continued maintenance cost. Closes rust-lang#70173. Closes rust-lang#92794. Closes rust-lang#87612. Closes rust-lang#82065. cc `@rust-lang/wg-inline-asm` r? `@Amanieu`
