Add a sugared version of ASTOwningResult::take,

The plain-pointer version is also added, but
that side seems to be seriously bitrotten.

Fix crash reported in <rdar://problem/6695527>. We now have
SVal::GetRValueSymbolVal do the checking if we can symbolicate a type instead of
having BasicStoreManager do it (which wasn't always doing the check
consistently). Having this check in SVal::GetRValueSymbolVal keeps the check in
one centralized place.

Also, have GCC tools lookup gcc program path.

when preprocessing a .S file, unknown directives should just be passed through,
and the token after the # should be expanded if it is not a valid directive.
This allows us to transform things like:

#define FOO BAR
# FOO

into # BAR, even though FOO is not normally expanded for directives.

 - This is not very precise, we use it to drive the "forward-to-gcc"
   predicate, when trying to talk to a generic gcc tool.

 - Slightly better than what ccc was doing, and should be good
   enough. Platforms which want a robust driver should implement a
   proper tool chain.

The scope representation can now be either a DeclContext pointer or a
Type pointer. This allows our nested-name-specifiers to retain more
information about the actual spelling (e.g., which typedef did the
user name, or what exact template arguments were used in the
template-id?). It will also allow us to have dependent
nested-name-specifiers that don't map to any DeclContext.

Driver: Add test case for -ccc-clang-archs (which, it turns out, was
inverted).

Driver: Add test case for various parts of binding (no-integrated-cpp,
-ccc-no-clang, -ccc-no-clang-cxx, -ccc-no-clang-cpp, -fsyntax-only).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67131 91177308-0d34-0410-b5e6-96231b3b80d8

don't crash when sentinel attribute is used on function without a prototype,
discovered as part of PR3817

Fix Type::getDesugaredType() to remove all direct sugar on
a type.  For example, if we have a typedef of a typeof of
int, we strip all the say down to int.  This allows us to
simplify the getAs* methods, and is the first step towards
fixing PR3817
