Most modules have such a blank line, but some don't. Inserting the blank
line makes it clearer that the `//!` comments are describing the entire
module, rather than the `use` declaration(s) that immediately follows.
This adds support for the simd variants of the pointer provenance
intrinsics, which are `simd_cast_ptr`, `simd_expose_addr`, and
`simd_from_exposed_addr`.
The preconditions for each intrinsic are adapted from rustc_codegen_llvm
to preserve compatibility. Each of these intrinsics are implemented as
calling the non-simd variant of each intrinsic on each lane.
This is enough to enable the UI test `ui/simd/intrinsic/ptr-cast.rs` to
pass.

They are also removed from the prelude as per the decision in
https://github.com/rust-lang/rust/issues/87228.
stdarch and compiler-builtins are updated to work with the new, stable
asm! and global_asm! macros.
* Implement basic support for inline assembly
* Disable LTO
We don't support it yet at all
* Handle `inout(reg) var` correctly
Turns out that `+` readwrite output registers cannot be tied with
input variables.
* Add limited support for llvm_asm!
* Handle CHANNEL correctly
* Add support for arbitrary explicit registers
* Handle symbols properly
* Add rudimentary asm tests
* Exclude llvm_asm! tests from tests runs
* Insert `__builtin_unreachable()` after diverging asm blocks
