the specific cases where an object type and the unqualified lookup
results are important. Fixes an assert and failed compile on
a testcase from PR7248.

diagnostic-capturing client lives as long as the ASTUnit itself
does. Otherwise, we can end up with crashes when we get a diagnostic
outside of parsing/code completion. The circumstances under which this
happen are really hard to reproduce, because a file needs to change
from under us.

of the enumerators rather than the actual expressible range. This is
great when dealing with opaque *values* of that type, but when computing
the range of the type for purposes of converting *into* it, it produces
warnings in cases we don't care about (e.g. enum_t x = 500;). Divide
the logic into these two cases and use the more conservative range for
targets.

NEON vector types need to be mangled in a special way to comply with ARM's ABI,
similar to some of the AltiVec-specific vector types. This patch is mostly
just renaming a bunch of "AltiVecSpecific" things, since they will no longer
be specific to AltiVec. Besides that, it just adds the new "NeonVector" enum.

out-of-line member template partial specializations until after the
class has been fully instantiated. This fixes a regression introduced
by r118454 (itself a fix for PR8001).

whether this should apply to attributes in general, but these are
a reasonable core.

using new/delete and OwningPtrs. After memory profiling Clang, I witnessed periodic leaks of these
objects; digging deeper into the code, it was clear that our management of these objects was a mess. The ownership rules were murky at best, and not always followed. Worse, there are plenty of error paths where we could screw up.
This patch introduces AttributeList::Factory, which is a factory class that creates AttributeList
objects and then blows them away all at once. While conceptually simple, most of the changes in
this patch just have to do with migrating over to the new interface. Most of the changes have resulted in some nice simplifications.
This new strategy currently holds on to all AttributeList objects during the lifetime of the Parser
object. This is easily tunable. If we desire to have more bound the lifetime of AttributeList
objects more precisely, we can have the AttributeList::Factory object (in Parser) push/pop its
underlying allocator as we enter/leave key methods in the Parser. This means that we get
simple memory management while still having the ability to finely control memory use if necessary.
Note that because AttributeList objects are now BumpPtrAllocated, we may reduce malloc() traffic
in many large files with attributes.
This fixes the leak reported in: <rdar://problem/8650003>

That bug concerned the well-formedness of code such as (&ovl)(a, b,
c). GCC rejects the code, while EDG accepts it. On further study of the
standard, I see no support for EDG's position: in particular, C++
[over.over] does not list this as a context where we can take the
address of an overloaded function, C++ [over.call.func] does not
reference the address-of operator at any point, and C++ [expr.call]
claims that the function argument in a call is either a function
lvalue or a pointer-to-function; (&ovl) is neither.

mangler. Now member functions and pointers thereof have their calling
convention mangled as __thiscall if they have the default CC (even though,
they technically still have the __cdecl CC).
