Title: Fix Issue 10897 - btc, btr and bts shouldn't be safe

This makes the functions `btc`, `btr` and `bts` `@system` as, just like `bt`, they aren't safe.

This change *compiles* just fine in both druntime and phobos, in `-unittest` mode, so it would seem the change doesn't break anything important safety wise.

However, it now fails to link. I think something needs to be changed in DMD itself too? Something about "intrisic"? I'd need help from one of the compilers guys in parallel to fix this. Anybody available? Pinging @9rnsr , @WalterBright .
