David Majnemer 88542a0a69 [SCCP] Remove duplicate code 
SCCP has code identical to changeToUnreachable's behavior, switch it
over to just call changeToUnreachable.

No functionality change intended.

David Majnemer 35c46d3e0b [InstCombine, SCCP] Consolidate code used to remove instructions 
InstCombine and SCCP both want to remove dead code in a very particular
way but using identical means to do so.  Share the code between the two.

No functionality change is intended.

David Majnemer b7d49268c2 [WinEH] Don't miscompile cleanups which conditionally unwind to caller 
A cleanup can have paths which unwind or end up in unreachable.
If there is an unreachable path *and* a path which unwinds to caller,
we would mistakenly inject an unwind path to a catchswitch on the
unreachable path.  This results in a verifier assertion firing because
the cleanup unwinds to two different places: to the caller and to the
catchswitch.

This occured because we used getCleanupRetUnwindDest to determine if the
cleanuppad had no cleanuprets.
This is incorrect, getCleanupRetUnwindDest returns null for cleanuprets
which unwind to caller.

Justin Lebar 3039a593db [CUDA] Make printf work. 
Summary:
The code in CGCUDACall is largely based on a patch written by Eli
Bendersky:
http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20140324/210218.html

That patch implemented an LLVM pass lowering printf to vprintf; this
one does something similar, but in Clang codegen.

Justin Lebar 3a5f5798a1 [CUDA] Die gracefully when trying to output an LLVM alias.

ptxas would choke.  Now we die before emitting any invalid code.

Joseph Tremoulet 23d02f6149 [ORC] Update ObjectTransformLayer signature 
Summary:
Update ObjectTransformLayer::addObjectSet to take the object set by
value rather than reference and pass it to the base layer with move

ObjectLinkingLayer.

Update the unit test to verify that ObjectTransformLayer's signature stays
in sync with ObjectLinkingLayer's.

Sanjay Patel a41ecae46e regenerate checks and note some near-term improvements 
For the moment, this file takes way too long to run (see inline comments), but
that should be a temporary problem. The fact that the compile time is so slow
for a target that doesn't support maskmov may be a bug worth investigating too.
