Refine placement of LangOptions object in CompilerInvocation by adding a new baseclass CompilerInvocationBase with a custom copy constructor.  This ensures that whenever the CompilerInvocation object's copy constructor is used we always clone the LangOptions object.

Simplify code for returning a struct for Darwin x86-32 ABI.  Use a better type for a function returning a struct containing only a pointer.  Handle the edge case of a struct containing only a float or double plus some dead padding instead of asserting.

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.

Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object.  I discovered that llvm::RefCountedBase<T> has
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.

In Microsoft mode, make "Unqualified lookup into dependent bases of class templates" works  inside default argument instantiation.

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.
