Remove a redundant query cache lookup while forcing In the serial compiler, we should never be trying to force a query node that has a cached value, because we would have already marked the node red or green when putting its value in cache. In the parallel compiler, we immediately re-check the cache while holding the state shard lock anyway, and trying to avoid that lock doesn't seem worthwhile.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
