The coredump logic is slightly different from other users in that it both stores mm flags and additionally sets and gets using masks. Since the MMF_DUMPABLE_* flags must remain as they are for uABI reasons, and of course these are within the first 32-bits of the flags, it is reasonable to provide access to these in the same fashion so this logic can all still keep working as it has been. Therefore, introduce coredump-specific helpers __mm_flags_get_dumpable() and __mm_flags_set_mask_dumpable() for this purpose, and update all core dump users of mm flags to use these.
