compiler,runtime: Determine if allocations need new pointers in runtime.
As the removed comment states, if the package being compiled played
certain tricks with pointers that looked like integers, the compiler
might allocate space for new pointers unnecessarily. Since the type
information on the heap is now precise, this logic can be moved to the
runtime.

compiler: Improve location info for function parameters.
Previously, errors reported for function parameters would point to the
beginning of the function declaration instead of to the column for the
given parameter.
