RUST-ANALYZER REWRITES MACRO EXPANSION INTERNALS, COMPILER PREDICATE CLEANUP LANDS

Rust-analyzer stripped out another batch of legacy `ExpandDatabase` queries overnight while the compiler team tackled redundant predicate handling in type checking.

The rust-analyzer team is methodically removing deprecated query group patterns, merging three separate PRs that eliminate `ExpandDatabase` queries [1] [2] [3] and refactor macro expansion methods for consistency [4]. This is part of a larger internal cleanup tracked in the analyzer's issue backlog. Meanwhile, the compiler team landed a predicate cleanup PR [5] that removes code paths treating generic predicates as clauses when only clauses are actually valid, tightening type system invariants. A rollup of 19 fixes also shipped [6], including view-type AST support, Enzyme on Apple silicon, and delegation improvements. The rust-analyzer subtree synchronized with the main compiler [7], and an allocator safety rewrite landed [8] defining "equivalent allocators" for stdlib correctness guarantees.
