Added some periods to some comments and added an overload for operator<< for type Sequence so I can print out Sequences in debug statements.

llvm-svn: 173831

Changed DoesObjCBlockEscape => DoesRetainableObjPtrEscape so I can use it to perform escape analysis of other retainable object pointers in other locations.

Provides the functionality for Clang change r172911 - I just had this still

The ARM and Thumb variants of LDREXD and STREXD have different constraints and
take different operands. Previously the code expanding atomic operations didn't
take this into account and asserted in Thumb mode.

actually have DEBUG statements. Also changed raw_ostream in said header
to be a forward declaration (removing an include).

This was missed since whenever I was including ObjCARCAliasAnalysis.h, I
was including ObjCARC.h before it which included these includes
(resulting in no compilation breakage).

The AttributeSetNode contains all of the attributes. This removes one (hopefully
last) use of the Attribute class as a container of multiple attributes.

This also required adding 2x headers Dependency Analysis.h/Provenance Analysis.h
and a .cpp file DependencyAnalysis.cpp to unentangle the dependencies inbetween
ObjCARCContract and ObjCARCOpts.

conditions are met:
1. They share the same operand and are in the same BB.
2. Both outputs are used.
3. The target has a native instruction that maps to ISD::FSINCOS node or
   the target provides a sincos library call.

Implemented the generic optimization in sdisel and enabled it for
Mac OSX. Also added an additional optimization for x86_64 Mac OSX by
using an alternative entry point __sincos_stret which returns the two
results in xmm0 / xmm1.

We no longer accept an encoded integer as representing all of the
attributes. Convert this via the AttrBuilder class into an AttributeSet with the
correct representation (an AttributeSetImpl that holds a list of Attribute
objects).

llvm-svn: 173750

Convert the AttrBuilder into a list of Attributes instead of one Attribute object that holds all of its attributes.
