Douglas Gregor 1f93ffb3e6 Centralize the management of CXXRecordDecl::DefinitionData's
HasTrivialConstructor, HasTrivialCopyConstructor,
HasTrivialCopyAssignment, and HasTrivialDestructor bits in
CXXRecordDecl's methods. This completes all but the Abstract bit and
the set of conversion functions, both of which will require a bit of
extra work. The majority of <rdar://problem/8459981> is now
implemented (but not all of it).

Douglas Gregor ec3bec0c7a Kill FunctionDecl's IsCopyAssignment bit; it duplicated what could
already be determined by isCopyAssignmentOperator(), and was set too
late in the process for all clients to see the appropriate
value. Cleanup only; no functionality change.

Douglas Gregor 009f69979a When dealing with an anonymous enumeration declared in function
prototype scope, temporarily set the context of the enumeration
declaration to the translation unit. We do the same thing for
parameters, until we have an actual function declaration on which to
hang them. Fixes <rdar://problem/8435682>.

There is more work to do in this area, since we have existing bugs
with tags being declared/defined in function parameter lists. This fix
is correct, and we'll end up extending it when we deal with those
existing bugs.

Argyrios Kyrtzidis 43b205796f Fix the memory leak of FloatingLiteral/IntegerLiteral.
For large floats/integers, APFloat/APInt will allocate memory from the heap to represent these numbers.
Unfortunately, when we use a BumpPtrAllocator to allocate IntegerLiteral/FloatingLiteral nodes the memory associated with
the APFloat/APInt values will never get freed.
I introduce the class 'APNumericStorage' which uses ASTContext's allocator for memory allocation and is used internally by FloatingLiteral/IntegerLiteral.

Alexis Hunt dcfba7b35b Generate Attr subclasses with TableGen.
Now all classes derived from Attr are generated from TableGen.
Additionally, Attr* is no longer its own linked list; SmallVectors or
Attr* are used. The accompanying LLVM commit contains the updates to
TableGen necessary for this.

Some other notes about newly-generated attribute classes:

 - The constructor arguments are a SourceLocation and a Context&,
   followed by the attributes arguments in the order that they were
   defined in Attr.td

 - Every argument in Attr.td has an appropriate accessor named getFoo,
   and there are sometimes a few extra ones (such as to get the length
   of a variadic argument).

Additionally, specific_attr_iterator has been introduced, which will
iterate over an AttrVec, but only over attributes of a certain type. It
can be accessed through either Decl::specific_attr_begin/end or
the global functions of the same name.

Douglas Gregor caa1bf434d Emit an error if an array is too large. We're slightly more strict
than GCC 4.2 here when building 32-bit (where GCC will allow
allocation of an array for which we can't get a valid past-the-end
pointer), and emulate its odd behavior in 64-bit where it only allows
63 bits worth of storage in the array. The former is a correctness
issue; the latter is harmless in practice (you wouldn't be able to use
such an array anyway) and helps us pass a GCC DejaGNU test.

Fixes <rdar://problem/8212293>.
