Move a few static functions from DiagnosticRenderer.cpp into SourceManager.
This simplifies the code a little bit, since these functions all took a
SourceManager parameter and called a bunch of methods on it, and makes
the functions available to other users.

Allow internal decls in inline functions if the function is in the main file.
This handles the very common case of people writing inline functions in their
main source files and not tagging them as inline. These cases should still
behave as the user intended. (The diagnostic is still emitted as an extension.)
I'm reworking this code anyway to account for C++'s equivalent restriction in
[basic.def.odr]p6, but this should get some bots back to green.

[analyzer] Return an UnknownVal when we try to get the binding for a VLA.
This happens in C++ mode right at the declaration of a struct VLA;
MallocChecker sees a bind and tries to get see if it's an escaping bind.

crash on valid without disturbing anything else for now.
[AST/libclang] Fix the selector locations that are reported for a
method definition that has its '{' attached to the method name without

With a method like:
-(id)meth{

the logic in ObjCMethodDecl that determined the selector locations got
confused because it was initialized based on an end location for '{' but
that end location changed to '}' after the method was finished.
Fix this by having an immutable end location for the declarator and
for getLocEnd() get the end location from the body itself.

[analyzer] Buffers passed to CGBitmapContextCreate can escape.
Specifically, although the bitmap context does not take ownership of the
buffer (unlike CGBitmapContextCreateWithData), the data buffer can be extracted
out of the created CGContextRef. Thus the buffer is not leaked even if its
original pointer goes out of scope, as long as
- the context escapes, or
- it is retrieved via CGBitmapContextGetData and freed.
Actually implementing that logic is beyond the current scope of MallocChecker,
so for now CGBitmapContextCreate goes on our system function exception list.

Warn when a static variable is referenced in a non-static inline function.
This is explicitly forbidden in C99 6.7.4p3. This is /not/ forbidden in C++,
probably because by default file-scope const/constexpr variables have internal
linkage, while functions have external linkage. There's also the issue of
anonymous namespaces to consider. Nevertheless, there should probably be a
similar warning, since the semantics of inlining a function that references
a variable with internal linkage do not seem well-defined.
