test: port 915/949 module-global access carriers to corpus fixtures
915_arr_module_index_run.c -> r915_arr_mod_idx0 (run), r915_arr_mod_
idx2 (run-exit 1), r915_arr_mod_idx4 (run-exit 6); the single-file
rows were already owned by r915_arr_local_* + test-data-byteid.
949_xmod_fnptr_const_run.c -> r949_xmod_fnptr_const_table (run),
r949_xmod_fnptr_wrong_sig, r949_xmod_fnptr_nonfn_dotted (error
'not assignable' both stages).
The 915 module rows upgrade from 994-delegated to per-fixture cs==ww
byte identity; 949's 2-file -I tree was not load-bearing — inline
packages exercise the same N_DOT &mod.fn mangle (mafn(leaf, module)).
