compiler: rename LayoutS to LayoutData

Bid `LayoutS` goodbye because it looks like a typo.

`LayoutS` is the last of the types that use the "`{TypeName}` is the interned type, `{TypeName}S` is the backing data that is interned" convention. This is pretty confusing to those not intimately familiar with the history of rustc's names for its types over time, and doubly so now that there are no other examples in the tree. Abolish this convention.
