When the header file search resolves a quoted include to a file in the
current directory, propagate the framework and in-index-header-map
from the including header's information down to the included header's
information. Fixes <rdar://problem/11261291>.

As with everything header-map related, we can't really test this in
isolation within Clang, so it's tested elsewhere.

When looking for the comment associated with a declaration, adjust the
'templated' declaration for a function or class template to refer to
the function or class template itself, to which the documentation will
be attached. Fixes PR13593.

[ms-inline asm] Have patchMSAsmStrings() return a vector or AsmStrings.

The AsmParser expects a single asm instruction, but valid ms-style inline asm
statements may contain  multiple instructions.

This happens with asm blocks

__asm {
  mov ebx, eax
  mov ecx, ebx
}

or when multiple asm statements are adjacent to one another

__asm mov ebx, eax
__asm mov ecx, ebx

and

__asm mov ebx, eax __asm mov ecx, ebx

Currently, asm blocks are not properly handled.

[analyzer] Don't strip CXXBaseObjectRegions when checking dynamic_casts.

...and /do/ strip CXXBaseObjectRegions when casting to a virtual base class.

This allows us to enforce the invariant that a CXXBaseObjectRegion can always
provide an offset for its base region if its base region has a known class
type, by only allowing virtual bases and direct non-virtual bases to form
CXXBaseObjectRegions.

This does mean some slight problems for our modeling of dynamic_cast, which
needs to be resolved by finding a path from the current region to the class
we're trying to cast to.

[analyzer] Handle dynamic_casts that turn out to be upcasts.

This can occur with multiple inheritance, which jumps from one parent to
the other, and with virtual inheritance, since virtual base regions always
wrap the actual object and can't be nested within other base regions.

This also exposed some incorrect logic for multiple inheritance: even if B
is known not to derive from C, D might still derive from both of them.

[analyzer] Be more careful when downcasting for devirtualization.

Virtual base regions are never layered, so simply stripping them off won't
necessarily get you to the correct casted class. Instead, what we want is
the same logic for evaluating dynamic_cast: strip off base regions if possible,
but add new base regions if necessary.

[analyzer] Reduce code duplication: make CXXDestructorCall a CXXInstanceCall.

While there is now some duplication between SimpleCall and the CXXInstanceCall
sub-hierarchy, this is much better than copy-and-pasting the devirtualization
logic shared by both instance methods and destructors.

An unfortunate side effect is that there is no longer a single CallEvent type
that corresponds to "calls written as CallExprs". For the most part this is a
good thing, but the checker callback eval::Call still takes a CallExpr rather
than a CallEvent (since we're not sure if we want to allow checkers to
evaluate other kinds of calls). A mistake here will be caught by a cast<> in
CheckerManager::runCheckersForEvalCall.

No functionality change.
