`expand_pattern()` has two callsites. One of them needs arena allocation, but the other does not. This commit moves the arena allocation out of the function. This avoids the allocation of many 4 KiB page arena chunks that only hold a single small allocation. It reduces the number of bytes allocated by up to 2% for various benchmarks, albeit without only a very small improvement in runtime.
resolve_vars_with_obligations, as it now also resolves const variables.
Clean up `contains()` `insert()` chains on HashSet They can be merged to a single `insert()` call, which may avoid double-hashing/lookup of the value.
