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.

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>
