<rdar://problem/11449953> Change Debugger::SetOutputFileHandle() so that it does not automatically initialize the script interpreter in order to transfer its output file handle to it
This should delay initialization of Python until strictly necessary and speed-up debugger startup
Also, convert formatters for SEL and BOOL ObjC data-types from Python to C++, in order to reap more performance benefits from the above changes

Adding the new has_children (or MightHaveChildren() in C++) for the existing synthetic children providers
In a few cases, the new call is going to be much more efficient than the previous num_children > 0 check
When the optimization was marginal (e.g. std::vector<>), the choice was to use num_children in order to keep
implementation details in one function instead of duplicating code

Next step is to provide test cases

llvm-svn: 166506

This commit enables the new HasChildren() feature for synthetic children providers
Namely, it hooks up the required bits and pieces so that individual synthetic children providers can implement a new (optional) has_children call
Default implementations have been provided where necessary so that any existing providers continue to work and behave correctly

Next steps are:
2) writing smart implementations of has_children for our providers whenever possible
3) make a test case
