For _XYZ, the type of VDATA is v4i32, because v3i32 doesn't exist.
The ADDR64 bit is not exposed. A simpler intrinsic that doesn't take
a resource descriptor might be nicer.
The maximum number of input SGPRs is bumped to 17.

This fixes some regressions in the piglit local memory store tests
introduced by recent commits which made the scheduler aware of the trans
slot.
It's not possible to test this using lit, because there is no way to
determine from the assembly dumps whether or not an instruction is in
the trans slot.
Even if this were possible, the test would be highly sensitive to
changes in the scheduler and might generate confusing false negatives.

We used to generate the compact unwind encoding from the machine
instructions. However, this had the problem that if the user used `-save-temps'
or compiled their hand-written `.s' file (with CFI directives), we wouldn't
generate the compact unwind encoding.
Move the algorithm that generates the compact unwind encoding into the
MCAsmBackend. This way we can generate the encoding whether the code is from a
`.ll' or `.s' file.

This pass was segfaulting when it ran into a non-intrinsic function
call. Function calls are not supported, so now instead of segfaulting,
we will get an assertion failure with a nice error message.
I'm not sure how to test this using lit.

Iterator of std::vector may be implemented as a raw pointer. In
this case begin iterators are rvalues and cannot be incremented.
For example, this is the case with STDCXX implementation of vector.

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

The logic in SIInsertWaits::getHwCounts() only really made sense for SMRD
instructions, and trying to shoehorn it into handling DS_WRITE_B32 caused
it to corrupt the encoding of that by clobbering the first operand with
the second one.
Undo that damage and only apply the SMRD logic to that.
Fixes some derivates related piglit regressions with radeonsi.

The SIInsertWaits pass was overwriting the first operand (gds bit) of
DS_WRITE_B32 with the second operand (value to write). This meant that
any time the value to write was stored in an odd number VGPR, the gds
bit would be set causing the instruction to write to GDS instead of LDS.

Now that compute support is better on SI, we can't continue using v16i8
for descriptors since this is also a legal type in OpenCL.
This patch fixes numerous hangs with the piglit OpenCL test and since
we now use a target specific DAG node for LOAD_CONSTANT with the
correct MemOperandFlags, this should also fix:

Using REG_SEQUENCE for BUILD_VECTOR rather than a series of INSERT_SUBREG
instructions should make it easier for the register allocator to coalasce
unnecessary copies.

SGPRs.
