std.meta: test that const and mut variables have different addresses
std.meta: test that const and mut variables have different addresses

We are checking that two identical, constant values, are stored at
different addresses.

But sharing a unique location doesn't look like something the compiler
wouldn't do.

It may make more sense to check that a const variable and a mutable
variable set to the same value have different addresses.
