Just merged in is a new compiler switch that instruments
generated code to collect statistics on memory allocation usage

-profile works.)
This was based on a prototype Andrei had written earlier.
Andrei and I suspect it can be of great use in figuring out why
a program may be excessively slow or consume excessive memory.
I encourage giving it a try on some non-trivial project, and
see if it gives useful information.
For now -profile=gc seems to count only the number of bytes
allocated, can we also have the number of how many times the
allocator is called? That's also pretty useful.
