dbc30dc5 - [IRGen] Cache the layout of the LLVM struct type for statically-initialized objects

[IRGen] Cache the layout of the LLVM struct type for statically-initialized objects Lazy emission of SIL global variables caused us to go through the creation of two different LLVM struct types for the same initialization, tripping an assertion in LLVM. Cache it along with other information about the static-initialized object rather than rebuilding it. Also fix the lazy_globals test to account for the laziness, generalizing it to also run on arm64 so I won't miss it locally.
