This is a duplicate of #29573 (comment) and #29574 (comment), but split out so that it doesn't get lost in the other discussions.

When initializing static data in a function (non-global) context, we generate code to construct the desired object. In some (most?) cases, it'd be preferable to have a static data symbol containing the desired object and then copy it into place using memmove/typedmemmove.

See those issues/comments for more details.
