Motiejus 6b8dc8dd9f stage0: prepare for IP gap closure (return_integer.zig)
- Enable module_root for sema unit tests in stages_test.zig, matching
  the Zig compiler which always creates std even with std_mod=null.
  The first 5 tests still pass since they only use pre-interned refs.

- Add analyzeMemoizedStateC infrastructure for resolving std.builtin
  BuiltinDecl entries (ExportOptions, CallingConvention, Type, etc.).
  Not yet triggered — the trigger path requires matching the Zig
  compiler's exact module loading order.

- Add --module-root flag to zig0 CLI for debugging IP entry comparison
  between the Zig compiler and C sema.

- Fix cppcheck warning: remove redundant !fi.is_inline check (already
  guarded by early return above).
