Rollup merge of #146323 - h3fang:issue-146230-fix, r=Amanieu
check before test for hardware capabilites in bits 32~63 of usize This commit tries to fix https://github.com/rust-lang/rust/issues/146230. `std::arch::is_aarch64_feature_detected` panics on aarch64 ILP32 targets. After some digging, the real problem is https://github.com/rust-lang/rust/blob/91edc3ebccc4daa46c20a93f4709862376da1fdd/library/std_detect/src/detect/os/linux/aarch64.rs#L210-L241 checks bits 32~63 of usize unconditionally on normal aarch64 LP64 target and aarch64 ILP32 target. Here I propose to move these to a block guarded by `#[cfg(target_pointer_width="64")]`. See rust-lang/rust#146230 for more detailed analysis. r? ```@Amanieu```
