Adds support for elementwise and aggregate splat casting struct types with bitfields. Replacing existing Flattening function which used to produce a list of GEPs representing a flattened object with one that produces a list of LValues representing a flattened object. The LValues can be used by EmitStoreThroughLValue and EmitLoadOfLValue, ensuring bitfields are properly loaded and stored. This also simplifies the code in the elementwise and aggregate splat casting functions. Closes #125986
