Use specific RSS check under 64-bit Scudo
Scudo is a hardened memory allocator that can be enabled on a per target basis,
and replaces malloc/free/etc with its own (go/scudo-allocator). It lives in
LLVM's compiler-rt project, along with ASan and the other sanitizers.
The 64-bit version of the allocator reserves (but doesn't commit) a large
portion of the address space, which is not compatible with the address space
limit enforced by RLIMIT_AS.
Scudo offers a function to enforce an upper RSS limit (note this is the actual
RSS of a process, not its AS), use it if running with 64-bit Scudo.
