5abd4662b8 Don't avoid cfi instructions on the bg/p.
The integrated assembler now works for ppc. Since this was the last use of the
bg/p predicate and Hal says that it is now dead, drop the predicate too.

122a970111 [SystemZ] Move sign_extend optimization to PerformDAGCombine
The target was marking SIGN_EXTEND as Custom because it wanted to optimize
certain sign-extended shifts.  In all other respects the extension is Legal,
so it'd be better to do the optimization in PerformDAGCombine instead.

69d2b2aa5a InstCombine: form shuffles from wider range of insert/extractelements
Sequences of insertelement/extractelements are sometimes used to build
vectorsr; this code tries to put them back together into shuffles, but
could only produce a completely uniform shuffle types (<N x T> from two
<N x T> sources).

This should allow shuffles with different numbers of elements on the
input and output sides as well.

7d7d99622f Replace PROLOG_LABEL with a new CFI_INSTRUCTION.
The old system was fairly convoluted:
* A temporary label was created.
* A single PROLOG_LABEL was created with it.
* A few MCCFIInstructions were created with the same label.

The semantics were that the cfi instructions were mapped to the PROLOG_LABEL
via the temporary label. The output position was that of the PROLOG_LABEL.
The temporary label itself was used only for doing the mapping.

The new CFI_INSTRUCTION has a 1:1 mapping to MCCFIInstructions and points to
one by holding an index into the CFI instructions of this function.

I did consider removing MMI.getFrameInstructions completelly and having
CFI_INSTRUCTION own a MCCFIInstruction, but MCCFIInstructions have non
trivial constructors and destructors and are somewhat big, so the this setup
is probably better.

The net result is that we don't create temporary labels that are never used.

4eb048a6f1 Support: split object format out of environment
This is a preliminary setup change to support a renaming of Windows target
triples.  Split the object file format information out of the environment into a
separate entity.  Unfortunately, file format was previously treated as an
environment with an unknown OS.  This is most obvious in the ARM subtarget where
the handling for macho on an arbitrary platform switches to AAPCS rather than
APCS (as per Apple's needs).

e54158504f [X86] Teach the DAGCombiner how to fold a OR of two shufflevector nodes.
This patch teaches the DAGCombiner how to fold a binary OR between two
shufflevector into a single shuffle vector when possible.

The rules are:
  1. fold (or (shuf A, V_0, MA), (shuf B, V_0, MB)) -> (shuf A, B, Mask1)
  2. fold (or (shuf A, V_0, MA), (shuf B, V_0, MB)) -> (shuf B, A, Mask2)

The DAGCombiner can take advantage of the fact that OR is commutative and
compute two possible shuffle masks (Mask1 and Mask2) for the resulting
shuffle node.

Before folding a dag according to either rule 1 or 2, DAGCombiner verifies
that the resulting shuffle mask is legal for the target.
DAGCombiner would firstly try to fold according to 1.; If not possible
then it will try to fold according to 2.
If both Mask1 and Mask2 are illegal then we conservatively don't fold
the OR instruction.
