This commit adds checks for overflow of args and env in Spawn(). It seems extremely unlikely that either of these values would overflow from a valid use case.

Fixes: #15622

If a program requires 2^31 number of arguments for its function, either it should be uimaginably complex, or buggy. In either case this check is great to have!
