Description
I get the following error with rust-analyzer:
macro invocation exceeds token limit: produced 997309 tokens, limit is 524288
But it's a working code which rustc can compile just fine. So I would like to increase the token limit for rust-analyzer.

Research direction
Start by locating where rust-analyzer enforces the 524288-token macro limit and compare that behavior with rustc. Confirm the reported case that produces 997309 tokens, and define done as accepting compilable code without this diagnostic while retaining appropriate limit behavior. No file or test is named, so repository exploration is required.
