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.

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.

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.

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.

succeeded or failed (but not if we crash). Add depfiles to the
failure result file list.

- With the current implementation of sys::Program this always printed "2".
- The command execution code will output the right number anyway (including the signal name).

When the solver and SValBuilder cannot reason about symbolic expressions (ex: (x+1)*y ), the analyzer conjures a new symbol with no ties to the past. This helps it to recover some path-sensitivity. However, this breaks the taint propagation.
With this commit, we are going to construct the expression even if we cannot reason about it later on if an operand is tainted.
Also added some comments and asserts.

a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation
objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed
that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted,
we can keep it around after the CompilerInvocation object goes away.
As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this
object may outlive the CompilerInvocation object.
This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to
mainline LLVM.

This is a little bit tricky because during default argument instantiation the CurContext points to a CXXMethodDecl but we can't use the keyword this or have an implicit member call generated.
This fixes 2 errors when parsing MFC code with clang.

into a module. This module can either be loaded from a module map in
the framework directory (which isn't quite working yet) or inferred
from an umbrella header (which does work, and replaces the existing
hack).
