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.

dde5790562 Hide FunctionTemplateDecl's specializations folding set as implementation detail and introduce
FunctionTemplateDecl::findSpecialization.

Redeclarations of specializations will not cause the previous decl to be removed from the set,
the set will keep the canonical decl. findSpecialization will return the most recent redeclaration.

47470f2f3f Hide the specializations folding sets of ClassTemplateDecl as an implementation detail (InsertPos
leaks though) and add methods to its interface for adding/finding specializations.

Simplifies its users a bit and we no longer need to replace specializations in the folding set with
their redeclarations. We just return the most recent redeclarations.

As a bonus, it fixes http://llvm.org/PR7670.

9e73cae25e When instantiating function definitions set parameter names to those used in template
The rationale is that we are copying the entire definition including
parameter names which may differ between the declaration and the
definition.

This is particularly important if any parameters are unnamed in the
declaration, as a DeclRef to an unnamed ParmVarDecl would cause the
pretty printer to produce invalid output.

36ea322579 Introduce Decl::hasBody() and FunctionDecl::hasBody() and use them instead of getBody() when we are just checking the existence of a body, to avoid de-serialization of the body from PCH.

f40c42f2cd Implement dependent alignment attribute support. This is a bit gross given the
current attribute system, but it is enough to handle class templates which
specify parts of their alignment in terms of their template parameters.

This also replaces the attributes test in SemaTemplate with one that actually
tests working attributes instead of broken ones. I plan to add more tests here
for non-dependent attributes in a subsequent patch.

Thanks to John for walking me through some of this. =D

b92ea59481 I hate this commit.
Revert much of the implementation of C++98/03 [temp.friend]p5 in
r103943 and its follow-ons r103948 and r103952. While our
implementation was technically correct, other compilers don't seem to
implement this paragraph (which forces the instantiation of friend
functions defined in a class template when a class template
specialization is instantiated), and doing so broke a bunch of Boost
libraries. 

Since this behavior has changed in C++0x (which instantiates the
friend function definitions when they are used), we're going to skip
the nowhere-implemented C++98/03 semantics and go straight to the
C++0x semantics.

This commit is a band-aid to get Boost up and running again. It
doesn't really fix PR6952 (which this commit un-fixes), but it does
deal with the way Boost.Units abuses this particular paragraph.
