PR10120: Make CodeGenModule::getVTableLinkage use NamedDecl::getLinkage to determine whether the vtable should be externally visible, instead of a rough approximation of it which messes up with templates.

While I'm here, zap the other user of isInAnonymousNamespace outside of Decl.cpp.

I believe, upon, careful review, that this code causes us to incorrectly
handle exception specifications of copy assignment operators in C++03
mode. However, we currently do not seem to properly implement the subtle
distinction between copying of members and bases made by implicit copy
constructors and assignment operators in C++03 - namely that they are
limited in their overload selection - in all cases. As such, I feel that
committing this code is correct pending a careful review of our
implementation of these semantics.

[analyzer] PR8962 again. Ban ParenExprs (and friends) from block-level expressions (by calling IgnoreParens before adding expressions to blocks). Undo 132769 (LiveVariables' local IgnoreParens), since it's no longer necessary.

Also, have Environment stop looking through NoOp casts; it didn't match the behavior of LiveVariables. And once that's gone, the whole cast block of that switch is unnecessary.

isn't yet used for the less controlled environments of initialization.

Also a few random text fixups.

llvm-svn: 132833

- Removed fix-it hints from template instaniations since changes to the
templates are rarely helpful.
- Changed the caret in template instaniations from the class/struct name to the
class/struct keyword, matching the other warnings.
- Do not offer fix-it hints when multiple declarations disagree.  Warnings are
still given.
- Once a definition is found, offer a fix-it hint to all previous declarations
with wrong tag.
- Declarations that disagree with a previous definition will get a fix-it hint
to change the declaration.

This is a follow-up to r132565, and should address the rest of PR9969:

Warn about cases such as

int foo(A a, bool b) {
 return a + b ? 1 : 2; // user probably meant a + (b ? 1 : 2);
}

also when + is an overloaded operator call.

Drop most of InitializationSequence::SequenceKind's values. They didn't really contain any information that the step array didn't contain too. This makes debugging dumps a bit less informative, but probably not significantly so. The advantage is that the redundancy is gone, so the code is easier to understand.
ReferenceBinding is still there, because it is used in some unclear code.

Remove all references to InitializationSequence::FailedSequence from outside SemaInit.cpp. Replace them with the boolean conversion or the new Failed() function. This is a first step towards removing InitializationSequence::SequenceKind. No functionality change.

compared even when one is a reference binding and the other is not
