<rdar://problem/
12523238> Commit 2 of 3
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

CMake: Fix public header search for generating Xcode/MSVC projects.
Previously, we only had support for one level of library under lib/,
with the existence of the two-level lib/StaticAnalyzer/* hardcoded in
the top-level CMakeLists.txt. This became a problem with split of
libRewrite into several libraries -- with the same sub-names as the
libraries in lib/StaticAnalyzer/.
Now, we match up anything under lib/ to the corresponding directory
in include/clang/.

Add a new warning -Wmissing-variable-declarations, to warn about variables
