3a57c37964 Extracted ObjCARCContract from ObjCARCOpts into its own file.
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.

8688a58c53 Teach SDISel to combine fsin / fcos into a fsincos node if the following
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.

8232ece5c1 Use an AttrBuilder to generate the correct AttributeSet.
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).

3c1c042a64 Fix gcc/printf/ISO C++ warning
Remove the use of the 't' length modifier to avoid a gcc warning. Based
on usage, 32 bits of precision is good enough for printing a stack
offset for a stack trace.

't' length modifier isn't in C++03 but it *is* in C++11. Added a FIXME
to reintroduce once LLVM makes the switch to C++11.

5ff776bfde This patch addresses bug 15031.
The common code in the post-RA scheduler to break anti-dependencies on the
critical path contained a flaw.  In the reported case, an anti-dependency
between the overlapping registers %X4 and %R4 exists:

	%X29<def> = OR8 %X4, %X4
	%R4<def>, %X3<def,dead,tied3> = LBZU 1, %X3<kill,tied1>

The unpatched code breaks the dependency by replacing %R4 and its uses
with %R3, the first register on the available list.  However, %R3 and
%X3 overlap, so this creates two overlapping definitions on the same
instruction.

The fix is straightforward, preventing selection of a register that
overlaps any other defined register on the same instruction.

The test case is reduced from the bug report, and verifies that we no
longer produce "lbzu 3, 1(3)" when breaking this anti-dependency.

Than (4GB!) long. Not only it takes forever to produce, the output file cannot be open, since its ginormous.

98b92f3bf5 Rewrite the removeAttr() method.
This now uses the AttributeSet object instead of the Attribute /
AttributeWithIndex objects. It's fairly simple now. It goes through all of the
subsets before the one we're modifying, adds them to the new set. It then adds
the modified subset (with the requested attributes removed). And then adds the
rest of the subsets.

73bc452bcd Remove a use of AttributeWithIndex.
We want to remove AttributeWithIndex because it provides a non-encapsulated view
of the AttributeSetImpl object. Instead, use accessor methods and iterators.

Eventually, this code can be simplified because the Attribute object will hold
only one attribute instead of multiple attributes.
