Significantly improve Atomic.h by pulling in code from libatomic_ops by HP.  This is a little outdated, but reasonably complete.

Add setters/getters to CXXMethodDecl so it can keep track of which virtual member functions it overrides (if any)

llvm-svn: 71968

narrower, so it doesn't catch expresions that aren't sub-expressions of
__extension__ operator.

llvm-svn: 71967

accordingly.

llvm-svn: 71966

correct.  No functionality change, as far as I know.

This makes me think that we should make hasExternalStorage perform this check...

Remove the volatile marker from the cas_flag typedef, fixing some warnings.  
 It's now the client's resposibility to add it in when needed

Implement instantiation of a few boring, simple expressions. I don't think these are testable yet, though.

alternatives, but please correct me if I'm wrong.

I eventually plan to assert in mergeTypes that we aren't in C++ mode 
because composite types are fundamentally not a part of C++. The 
remaining callers for code in the regression tests are 
Sema::WarnConflictingTypedMethods and CodeGenFunction::EmitFunctionProlog;
I'm not quite sure what the correct approach is for those callers.

types.

This patch isn't quite ideal in that it eliminates the warning for 
constructs like "int a = {1};", where the braces are in fact redundant.  
However, that would have required a bunch of refactoring, and it's 
much less likely to cause confusion compared to redundant nested braces.

Back out the thread-safe ManagedStatic for now.  Too many people have too many problems with it for the moment.

Fix: <rdar://problem/6893565> False positive: don't flag leaks for return types that cannot be determined to be CF types

Fix another bug in BugReporter where we wouldn't always select the bug report in a bug equivalence class with the shortest path.
