  extern void *malloc (__SIZE_TYPE__ __size) throw () __attribute__

Clean up ownership of 'AttributeList' objects in Parser.  Apparently

these objects at all.  AttributeList objects would get leaked on both
error and non-error paths.

Note: I introduced the usage of llvm::OwningPtr<AttributeList> to
manage these objects, which is particularly useful for methods with
multiple return sites.  In at least one method I used them even when
they weren't strictly necessary because it clarified the ownership
semantics and made the code easier to read.  Should the excessive
'take()' and 'reset()' calls become a performance issue we can always
