The change was made for readability, as the PropagationInfo objects don't
always contain a status.  This is submitted as a separate patch because it
touches a lot of lines and I don't want it cluttering up the next patch.

CodeGenFunction is run on only one function - a new object is made for
each new function. I would add an assertion/flag to this effect, but
there's an exception: ObjC properties involve emitting helper functions
that are all emitted by the same CodeGenFunction object, so such a check
is not possible/correct.

Now that fast-isel is in better shape, we can enable the machine
verifier for these tests, too.

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

Constant pool and global value reference instructions need more
restricted register classes than plain GPR.

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

llvm-svn: 189267

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).

- __func__ or __FUNCTION__ returns captured statement's parent

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
