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.
