Unfortunately, C still lacks a standard function for pause (x86, sparc) or yeild (arm) instructions, for use in spin lock or CAS loops. BIND has its own based on vendor intrinsics or inline asm. Previously, it was buried in the `isc_rwlock` implementation. This commit renames `isc_rwlock_pause()` to `isc_pause()` and moves it into <isc/pause.h>. This commit also fixes the configure script so that it detects ARM yield support on systems that identify as `aarch*` instead of `arm*`. On 64-bit ARM systems we now use the ISB (instruction synchronization barrier) instruction in preference to yield. The ISB instruction pauses the CPU for longer, several nanoseconds, which is more like the x86 pause instruction. There are more details in a Rust pull request, which also refers to MySQL making the same change: https://github.com/rust-lang/rust/pull/84725
