Subzero: Refine the memory usage report with -szstats .
The problem is that the memory usage that comes from the -track-memory option is not very well-defined (it's a hidden LLVM option after all). It gives an OK sense of memory growth over time, but sometimes we really want to know how much CFG-local arena memory was allocated for a particular function.
To help with this, we add another row to the stats output, giving the MB size of the CFG arena at the end of translating the method.
