caff247882 Add feature to diagnostics that will provide more information on function 
pointer mismatch.  Cases covered are: initialization, assignment, and function
arguments.  Additional text will give the extra information about the nature
of the mismatch: different classes for member functions, wrong number of
parameters, different parameter type, different return type, and function
qualifier mismatch.

8ad3bab505 [libclang] Fix operations (token annotation, getting cursor, etc.) with a file region 
inside an objc container that "contains" other file-level declarations.

When getting the array of file-level declarations that overlap with a file region,
we failed to report that the region overlaps with an objc container, if
the container had other file-level declarations declared lexically inside it.

Fix this by marking such declarations as "isTopLevelDeclInObjCContainer" in the AST
and handling them appropriately.

c445be4b4b AAPCS compliance - 32-bit wchar_t should be unsigned for both aapcs and aapcs-linux. 
Original behaviour of defining wchar_t as signed int has been kept for apcs-gnu as I don't have any spec for this to validate against.

9a56882e53 Add driver arguments -ftemplate-depth=N and -fconstexpr-depth=N, with the same 
semantics and defaults as the corresponding g++ arguments. The historical g++
argument -ftemplate-depth-N is kept for compatibility, but modern g++ versions
no longer document that option.

Add -cc1 argument -fconstexpr-depth N to implement the corresponding
functionality.

The -ftemplate-depth=N part of this fixes PR9890.
