identifier, we may have a Sema object but no translation unit scope
(because parsing is finished). In this case, we still need to update
the IdResolver, which might still be used when writing a PCH
containing another PCH (without chaining). This bug manifested as a
failure with precompiled preambles.
Also, add a little environment-variable-sensitive logging for
libclang.

The canonical FunctionTemplateDecl contains the specializations but we cannot use getCanonicalDecl on Template because it may still be initializing.
Write and read it from PCH.

Another beating by boost in this test case: http://llvm.org/PR8117
A function specialization wasn't properly initialized if it wasn't canonical.
I wish there was a nice little test case but this was boost.

covered by individual case statements. Flow-based analyses may wish to consult this information,
and recording this in the AST allows us to obviate reconstructing this information later when
we build the CFG.

PCH got a severe beating by the boost-using test case reported here: http://llvm.org/PR8099
Fix issues like:
-When PCH reading, make sure Decl's getASTContext() doesn't get called since a Decl in the parent hierarchy may be initializing.
-In ASTDeclReader::VisitFunctionDecl VisitRedeclarable should be called before using FunctionDecl's isCanonicalDecl()
-In ASTDeclReader::VisitRedeclarableTemplateDecl CommonOrPrev must be initialized before anything else.

three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.
Several related changes here:
- Cursor visitation of the three AST nodes for using declarations
- Proper source-range computation for these AST nodes
- Using declarations have no USRs, since they don't actually declare
any entities.

suppressing USRs). Also, fix up the source location information for
using directives so that the declaration location refers to the
namespace name.

(and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in
an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced
in both the @interface and class extensions. The latter is needed for semantic analysis/codegen, while the former is
needed to maintain the lexical information of the original source.

aliases. Previously, the location of the alias was at the "namespace"
keyword. Now, it's on the identifier being declared (as is the custom
for Clang), and we keep a separate source location for the "namespace"
keyword.
Also, added a getSourceRange() member function to NamespaceAliasDecl
to correctly compute the source range.
Finally, removed a bunch of setters from NamespaceAliasDecl and gave
ASTReaderDecl friendship so that it could set the corresponding fields
directly.

For large floats/integers, APFloat/APInt will allocate memory from the heap to represent these numbers.
Unfortunately, when we use a BumpPtrAllocator to allocate IntegerLiteral/FloatingLiteral nodes the memory associated with
the APFloat/APInt values will never get freed.
I introduce the class 'APNumericStorage' which uses ASTContext's allocator for memory allocation and is used internally by FloatingLiteral/IntegerLiteral.
