Do not spill operand debuginfo to stack for AArch64 SVE predicates `<vscale x N x i1>` where `N != 16` This pull request tries to fix rust-lang/rust#150419. The debuginfo for AArch64 SVE predicates `<vscale x N x i1>` where `N != 16` should be ignored by this [commit](https://github.com/rust-lang/rust/pull/143924/changes/89eea57594e3e1d8e618dd530ea1c8e7c9b4c7a4). https://github.com/rust-lang/rust/blob/89eea57594e3e1d8e618dd530ea1c8e7c9b4c7a4/compiler/rustc_codegen_ssa/src/mir/debuginfo.rs#L438-L452 But in line 446, the `marker_type.kind()` is `ty::Bool` instead of `ty::Slice`, so the code doesn't work as intended. This pull request uses the [`Ty::scalable_vector_element_count_and_type`](https://github.com/rust-lang/rust/blob/main/compiler/rustc_middle/src/ty/sty.rs#L1272) method to fix the condition checks for `<vscale x N x i1>` where `N != 16` and add a compiletest for this case.
