Get the register class right for the TST instruction. This keeps the
machine verifier happy, enabling us to turn it on for another test.

The create machine code wasn't properly in SSA, which the machine verifier
properly complains about. Now that fast-isel is closer to verifier clean,
errors like this show up more clearly.
Additionally, the Thumb pseudo tPICADD was used for both ARM and Thumb
mode functions, which is obviously wrong. Fix that along the way.
Test case is part of the following commit which will finish making an
additional fast-isel test verifier clean an enable it for the
regression test suite. This commit is separate since its not just
a verifier cleanup, but an actual correctness issue.

Added a command line option "-remove-change-desc-files" that triggers
the deletion of the change description files after merging and applying
regardless of success.

Incremental improvement to fast-isel for PPC64. This allows us to
select on ret, sext, and zext. Filling in sext/zext improves some of
the existing logic in handling compare-immediates that needed extends.
A simplified return convention for fast-isel is also added to the
PPC64 calling conventions. All call/return processing for DAG
selection is handled with custom code, so there isn't an existing CC
to rely on here. The include of PPCGenCallingConv.inc causes compiler
warnings due to the 32-bit calling conventions that are not used, so
the dummy function "usePPC32CCs()" is added here to silence those.
Test cases for the return and extend logic are added.

If we have a binary operation like ISD:ADD, we can set the result type
equal to the result type of one of its operands rather than using
TargetLowering::getPointerTy().
Also, any use of DAG.getIntPtrConstant(C) as an operand for a binary
operation can be replaced with:
DAG.getConstant(C, OtherOperand.getValueType());

This adds minimal support to the SelectionDAG for handling address spaces
with different pointer sizes. The SelectionDAG should now correctly
lower pointer function arguments to the correct size as well as generate
the correct code when lowering getelementptr.
This patch also updates the R600 DataLayout to use 32-bit pointers for
the local address space.
v2:
- Add more helper functions to TargetLoweringBase
- Use CHECK-LABEL for tests

Xcode always puts executable targets in the directory
bin/<Config>. When building separate LLVM and Clang projects for
Xcode, this prevents the CMake-configured project for Clang from
finding llvm-tblgen. Add a symlink so that tblgen executables are
always available in bin/ (regardless of the configuration LLVM is
built with).

Handle calls to Die() from the tracer thread. Fixes a bug where a CHECK
could fail in the tracer thread, resulting in a call to AsanDie. The tracer
thread then exited and the parent process continued execution despite its
address space being in an unusable state.

The cleanup includes :-
* Rename ambiguous Header class to ELFHeader
* Convert Chunk contentype and kind to be a enumerated class
* Remove functions that are not being used, avoids future confusion

They were mostly copy&paste of each other, move it to CodeGenFunction. Of course
the two implementations have diverged over time; the one in CGExprCXX seems to
be the more modern one so I picked that one and moved it to CGClass which feels
like a better home for it. No intended functionality change.

First chunk of actual fast-isel selection code. This handles direct
and indirect branches, as well as feeding compares for direct
branches. PPCFastISel::PPCEmitIntExt() is just roughed in and will be
expanded in a future patch. This also corrects a problem with
selection for constant pool entries in JIT mode or with small code
model.

-Assembly parser now properly check the size of the memory operation specified in intel syntax. So 'mov word ptr [5], al' is no longer accepted.
-x86-32 disassembly of these instructions no longer sign extends the 32-bit address immediate based on size.
-Intel syntax printing prints the ptr size and places brackets around the address immediate.
Known remaining issues with these instructions:
-Segment override prefix is not supported. PR16962 and PR16961.
-Immediate size should be changed by address size prefix.

Summary:
Previously the backend wouldn't get to see the underlying GlobalValue
that corresponds to the template argument because it would be hidden by
a cast at the IR level. Instead strip the pointer casts off of the
value until we see the underlying GlobalValue.
