Move two-word KECCAK staging memory expansion into MIR for the specialized helper paths. This lets the JIT emit the overflow, maximum-size, expansion, and memory-size update once before calling a no-expand runtime helper. Keep the existing runtime-expanding helpers for fallback users, add no-expand helper variants for the JIT macro-op path, and cover calldata-slot memory expansion failure semantics with a regression test.
Reuse the memory base returned by the expanding two-word KECCAK helper instead of reloading it in the shared hashing path. Document the no-expand helper precondition and add a nonzero staging-base regression test for the calldata-slot macro helper.
