SH profiling redux

[Kris Warkentin]

Well, I tried a few more test cases and it looks like profiling is working
more or less alright.  I'm still getting the 'no call graph' data thing on
some apps but that may be something to do with our mcount.

The compiler blows up on this file - I've put the error messages afterwards:

#include <iostream>

int
main()
{
 std::cout << "Hello World!" << std::endl;
 return 0;
}

We're using the Dinkum headers.  If anyone is interested, I'll post the
assembly output as well.  It's definitely my profiled stuff that's causing
it since it works fine without -p but I'm not sure what's wrong with what is
being emitted.

cheers,

Kris
