ConvertType on InitListExprs as they are being converted.  This is
needed for a forthcoming patch, and improves the IR generated anyway
(see additional type names in testcases). 

This patch also converts a bunch of std::vector's in CGObjCMac to use
C arrays.  There are a ton more that should be converted as well.

to single out Blaine Garst and Patrick Beard for their contributions.

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.

Match llvm-gcc's string literals alignment by forcing alignment on string literals to 1.  This can significantly impact the size of the string data, and as far as I know, the alignment doesn't help performance.  rdar://9078969 .

 - New isDefined() function checks for deletedness
 - isThisDeclarationADefinition checks for deletedness
 - New doesThisDeclarationHaveABody() does what
   isThisDeclarationADefinition() used to do
 - The IsDeleted bit is not propagated across redeclarations
 - isDeleted() now checks the canoncial declaration
 - New isDeletedAsWritten() does what it says on the tin.
 - isUserProvided() now correct (thanks Richard!)

This fixes the bug that we weren't catching

void foo() = delete;
void foo() {}

as being a redefinition.

Add an implementation of thunks for varargs methods.  The implementation is a bit messy, but it is correct as long as the method in question doesn't use indirect gotos.  A couple of possible alternative implementations are outlined in FIXME's in this patch. rdar://problem/8077308 .

Add -fdelayed-template-parsing option. Using this option all templated function definitions are parsed at the end of the translation unit only if it is required by an actual instantiation. As such all the symbols of the TU are available during name lookup.

Using this flag is necessary for compatibility with Microsoft template code.
This also provides some parsing speed improvement.

The idea is that you can create a VarDecl with an unknown type, or a
FunctionDecl with an unknown return type, and it will still be valid to
access that object as long as you explicitly cast it at every use.  I'm
still going back and forth about how I want to test this effectively, but
I wanted to go ahead and provide a skeletal implementation for the LLDB
folks' benefit and because it also improves some diagnostic goodness for
placeholder expressions.

lookup of explicit visibility so that we search for both an explicit
VisibilityAttr and an appropriate AvailabilityAttr, favoring the
VisibilityAttr if it is present.
