MariaDB is compiled with C++ exceptions enabled, and that disallows
some optimizations (e.g. the stack must always be unwinding-safe). By
adding `noexcept` to functions that are guaranteed to never throw,
some of these optimizations can be regained. Low-level locking
functions that are called often are a good candidate for this.
This shrinks the executable a bit (tested with GCC 14 on aarch64):
