Add preamble syntax for declaring static and dynamic heaps, and update the langref section on heaps. Add IR support for heap references. Remove the heap_load and heap_store as discussed in #144. We will use heap_addr along with native load and store instructions in their place. Add the heap_addr instruction and document its bounds checking semantics.
