Alex Lorenz d900714299 [Sema] Formatting warnings should see through Objective-C message sends 
This commit improves the '-Wformat' warnings by ensuring that the formatting
checker can see through Objective-C message sends when we are calling an
Objective-C method with an appropriate format_arg attribute.

Artem Dergachev bba497fb65 [analyzer] Add StdLibraryFunctions checker. 
This checker does not emit reports, however it influences the analysis
by providing complete summaries for, or otherwise improving modeling of,
various standard library functions.

This should reduce the number of infeasible paths explored during analysis.
The custom function summary format used in this checker is superior to
body farms by causing less unnecessary state splits,
which would result in better analysis performance.

Alex Lorenz cb642b9136 [Sema][TreeTransform] Re-create DesignatedInitExpr when a field designator 
has no field declaration.

This commit fixes an invalid Winitializer-overrides warning that's shown
when analyzing a second (or any after the first) instantiation of a designated
initializer. This invalid warning is fixed by making sure that a
DesignatedInitExpr is rebuilt by the tree transformer when it has a field
designator whose FieldDecl* hasn't been yet initialized. This ensures that a
different DesignatedInitExpr is processed by Sema for every instantiation, and
thus the invalid warning is avoided.

With this patch, all intrinsics in this file (with an exception of a handful of a recently added ones) will be documented. I will send out a patch for 4 missining intrisics later.

The doxygen comments are automatically generated based on Sony's intrinsics document.

I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream. This patch was internally reviewed by Yunzhong Gao.
