This is stuff I noticed while working on #120932, but it's orthogonal to that PR.

We already check_static each operand we see, so I don't understand why this was checked again here.

Here this was not a literal duplicate -- the other error is "thread-local statics cannot be accessed". So the old error was even wrong, since STATIC_VAR_2 is a thread-local static, not a regular static, and saying that this is "unstable" and needs the const_refs_to_static feature gate is not correct.
