Added gdb-remote $qMemoryRegionInfo tests for heap and stack.
Added two new tests: one to verify that a test exe heap address
returned is readable and writeable, and a similar one to verify
a test exe stack address is readable and writeable.
Ran the main.cpp test exe code through the Xcode re-indenter.
I was using TextMate to edit the test's C++ code alongside the
Python code but last check-in found that it was not handling
tabs/indentation the way I am intending it.
Modified test exe to require C++11.
Refactored gdb remote python code's handling of memory region
info into more re-usable methods.
