a85c1469c7 When building RTTI descriptors for pointer types, we need to get the unqualified array type and the qualifiers from it.

48bf349471 Fix -fno-rtti -fexceptions by forcing the emission of (non-"builtin") RTTI 
when used by the exceptions routines.  Fixes PR 6974.

eadd3cace9 Eliminate excessive PCH deserialization caused by the search for 
__cxxabiv1::__fundamental_type_info in every translation
unit. Previously, we would perform name lookup for
__cxxabiv1::__fundamental_type_info at the end of IRGen for a each
translation unit, to determine whether it was present. If so, we we
produce type information for all of the fundamental types. However,
this name lookup causes PCH deserialization of a significant part of the
translation unit, which has a woeful impact on performance.

With this change, we now look at each record type after we've
generated its vtable to see if it is
__cxxabiv1::__fundamental_type_info. If so, we generate type info for
all of the fundamental types. This works because
__cxxabiv1::__fundamental_type_info should always have a key function
(typically the virtual destructor), that will be defined once in the
support library. The fundamental type information will end up there.

Fixes <rdar://problem/7840011>.

d7f18dd750 Drastically simplify the computation of linkage for typeinfo by using 
the existing (and already well-tested) linkage computation for types,
with minor tweaks for dynamic classes and (pointers to) incomplete
types. Fixes PR6597.

67da35c832 Extract a common structure for holding information about the definition 
of a C++ record.  Exposed a lot of problems where various routines were
silently doing The Wrong Thing (or The Acceptable Thing in The Wrong Order)
when presented with a non-definition.  Also cuts down on memory usage.

2a34df3264 Fix linkage for RTTI names by re-using the logic for computing the 
linkage of vtables. Before this, we were emitting RTTI names for
template instantiations with strong external linkage rather than with
weak ODR linkage.

would have a higher respect for its own code. This is getting old, is this
