Eli Friedman 2696b1e25e Default builtin creation to off; we don't really want to be doing it 
without a relevant source location anyway.  Fixes the issue with weird 
warnings when including objc/Object.h on OS X.

Mike Stump cbc2bcaf17 As an optimization, we maintain a cache of generated 
___Block_byref_id_object_dispose and ___Block_byref_id_object_copy
functions so that we can simply reuse instead of creating a new one.
Additionally, add an assert to ensure no one yet tries to align a
__block variable beyond the alignment of a pointer as the codegen is
incomplete.

Daniel Dunbar 4be99ff767 ABI handling: Fix nasty thinko where IRgen could generate an out-of-bounds read 
when generating a coercion for ABI handling purposes.
 - This may only manifest itself when building at -O0, but the practical effect
   is that other arguments may get clobbered.

Douglas Gregor b7ae10f764 Several improvements to template argument deduction: 
- Once we have deduced template arguments for a class template partial
    specialization, we use exactly those template arguments for instantiating
    the definition of the class template partial specialization.
  - Added template argument deduction for non-type template parameters.
  - Added template argument deduction for dependently-sized array types.

With these changes, we can now implement, e.g., the remove_reference
type trait. Also, Daniel's Ackermann template metaprogram now compiles
properly.

Fariborz Jahanian 2d725b19da This patch attempts to fix the merging of __strong/__weak attributes 
in merge_types. It is incomplete. We probably want to issue 
a warning if user attempts to change the attribute from __weak to
__strong or vice-vera. It also assumes that a __weak/__strong
attribute can not be specified with other (currently one) type
attriute.

Eli Friedman dcca6333c6 Disable type merging with gc attributes. This has a number of nasty 
properties at the moment:

1. It allows stuff like "__strong id x; __weak id x;".

2. For constructs like "__strong id x; id x;", subsequent references to 
x lose the objc_gc attribute.

3. This incorrectly allows merges involving the address_space attribute.

4. Constructs like "id x; /* some code using x */ __weak id x;" don't 
apply the objc_gc attribute consistently to all uses of x.

The first three can probably be fixed relatively easily; the fourth 
would be extremely difficult to fix.

or more declarations using that TagDecl directly.  Change
SuppressTypeSpecifiers to the more general SuppressSpecifiers, and 
use it to suppress stuff like "typedef" and "extern".  Replace 
OwnedTag with SuppressTag, since it's more convenient to print 
declarations from DeclPrinter at the moment.
