1bff0b83b0 Fix another isFirstClassType that now needs to be isSingleValueType. 
This fixes recent CBE regressions.

6a45cf9dd6 Add support for multiple-return values in inline asm. This should 
get inline asm working as well as it did previously with the CBE
with the new MRV support for inline asm.

768b6f281e Add CommonLinkage; currently tentative definitions 
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

bab18cae46 Clean up the use of static and anonymous namespaces. This turned up 
several things that were neither in an anonymous namespace nor static
but not intended to be global.

it causes compile errors.

4949a9c308 Partial CBackend support for 128-bit integers. This is needed 
now that llvm-gcc is lowering appropriately-sized struct returns
to i128 on x86-64.

22002efa15 A quick nm audit turned up several fixed tables and objects that were 
marked read-write. Use const so that they can be allocated in a
read-only segment.

7925cc72c0 Reimplement the parameter attributes support, phase #1. hilights: 
1. There is now a "PAListPtr" class, which is a smart pointer around
   the underlying uniqued parameter attribute list object, and manages
   its refcount.  It is now impossible to mess up the refcount.
2. PAListPtr is now the main interface to the underlying object, and
   the underlying object is now completely opaque.
3. Implementation details like SmallVector and FoldingSet are now no
   longer part of the interface.
4. You can create a PAListPtr with an arbitrary sequence of
   ParamAttrsWithIndex's, no need to make a SmallVector of a specific 
   size (you can just use an array or scalar or vector if you wish).
5. All the client code that had to check for a null pointer before
   dereferencing the pointer is simplified to just access the 
   PAListPtr directly.
6. The interfaces for adding attrs to a list and removing them is a
   bit simpler.

Phase #2 will rename some stuff (e.g. PAListPtr) and do other less 
invasive changes.

e9aa391b61 Several changes: 
* Simplify handling of byval, making it easier to understand and more 
    consistent.  This fixes PR2065.
  * Clean up and simplify handling of GEPs.  I can actually understand it now!
  * Implement support for GEP'ing into vectors, this fixes
    SingleSource/UnitTests/Vector/build2 among others.

da54523742 I cannot find a libgcc function for this builtin. Therefor expanding it to a noop (which is how it use to be treated). If someone who knows the x86 backend better than me could tell me how to get a lock prefix on an instruction, that would be nice to complete x86 support.

88a41c672b Enabling the target-independent garbage collection infrastructure by hooking it 
up to the various compiler pipelines.

This doesn't actually add support for any GC algorithms, which means it 
temporarily breaks a few tests. To be fixed shortly.

1e2e4972ff Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

906683b821 Work around a GCC bug, producing this code: 
unsigned char *llvm_cbe_X;
...
  llvm_cbe_X = 0; *((void**)&llvm_cbe_X) = __builtin_stack_save();

instead of:

  llvm_cbe_X = __builtin_stack_save();

3602011bec Fix PR1146: parameter attributes are longer part of 
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.
