This commit will use the memory layout information for heap allocations added in the previous commit to determine LLVM types, instead of guessing their types based on the content. This fixes a bug in which recursive data structures (such as doubly linked lists) would result in a compiler stack overflow due to infinite recursion. Not all heap allocations have a memory layout yet, but this can be incrementally fixed in the future. So far, this commit should fix (almost?) all cases of this stack overflow issue.
