Checking in fixes that I used to track down a leaking module. The heap module can now search the vm regions with the --vm-regions options to any of the heap functions. This is currently slow and often will time out when run on a large program since our user expression timeout is set to 500000 usec. We need to add an API to LLDB where we can specify the timeout for an expression.

Added "heap" command to get info on all allocations on the heap. Currently only objective C objects are supported since they are easy to detect.

Playing around with "objc_refs" over the weekend and improved it to work on a large ObjC program without running into expression timeouts. Now we get a full list of ObjC classes using a runtime function and then qsort the result. Also added code that can count all instances of each ObjC on the heap and also the total byte sizes for the object allocations.

superclasses on top of finding the exact class. The current attempt is still
too slow, but it lays the groundwork.

Fixed an issue where not all text would always be seen when running any of the functions in heap.py in Xcode. Now we put the text directly into the command result object and skip STDIO since we have issues with STDIO right now in python scripts.
Also fixed an issue with the "--stack-history" option where MallocStackLoggingNoCompact was assumed to have to be enabled... It doesn't, just MallocStackLogging.

Added a new "objc_refs" command that will track down all allocations on the heap that have the "isa" for the objective C class at offset zero. This will need to be improved to deal with KVO classes, but it is a start. It also disallows looking up a pointer value of zero since that would return way too many matches.
