Reapply r151702 with a small fix for a failure to cut and paste correctly. Still rdar://10900684 llvm-svn: 151838

Teach Expr::HasSideEffects about all the Expr types, and fix a bug where it was mistakenly classifying dynamic_casts which might throw as having no side effects. Switch it from a visitor to a switch, so it is kept up-to-date as future Expr nodes are added. Move it from ExprConstant.cpp to Expr.cpp, since it's not really related to constant expression evaluation. Since we use HasSideEffect to determine whether to emit an unused global with internal linkage, this has the effect of suppressing emission of globals in some cases. I've left many of the Objective-C cases conservatively assuming that the expression has side-effects. I'll leave it to someone with better knowledge of Objective-C than mine to improve them. llvm-svn: 161388

extern "C" auto cvar = []{};
int a() { return []{ return 1; }(); }
int b(int x) { return [x]{return x;}(); }
int c(int x) { return [&x]{return x;}(); }
struct D { D(); D(const D&); int x; };
Only emit debug info for implicit members that actually get codegen, not just ODR use. This includes special members (copy/default ctor, copy assign, default ctor) and template specializations for member function templates. Good for a 5% decrease (1.80 to 1.71 GB) in size on Clang+LLVM's .dwo files (when using fission). llvm-svn: 188085

Emit DeferredDeclsToEmit in a DFS order. Currently we emit DeferredDeclsToEmit in reverse order. This patch changes that. The advantages of the change are that * The output order is a bit closer to the source order. The change to test/CodeGenCXX/pod-member-memcpys.cpp is a good example. * If we decide to deffer more, it will not cause as large changes in the estcases as it would without this patch. llvm-svn: 226751
