GCC 12 has added a warning -Winterference-size when these are used without specifying its value. see 

https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Winterference-size

This is causing a build failure on aarch64 since hardware_constructive_interference_size defaults to 256 on this platform.

we get error

In file included from src/mongo/s/commands/cluster_find_cmd.cpp:39:
src/mongo/db/stats/counters.h:185:47: error: static assertion failed: cache line spill
 185 |     static_assert(sizeof(decltype(_together)) <= stdx::hardware_constructive_interference_size,
     |                   ~~~~~~~~~~~~~~~~~~~~~~~~~~~_^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I think the assumption about these defaults are perhaps not right in mongodb, I also opened a gcc bug where there is some discussion around it.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105251

perhaps 'struct Together' should be aligned to hardware_constructive_interference_size to promote true sharing and not to CacheAligned which is aligned to hardware_destructive_interference_size
