35ad126c78 Let llvm.invariant.group.barrier accepts pointer to any address space
llvm.invariant.group.barrier may accept pointers to arbitrary address space.

This patch let it accept pointers to i8 in any address space and returns
pointer to i8 in the same address space.

3c8dd1f596 Fix pointer EVT in SelectionDAGBuilder::visitAlloca
SelectionDAGBuilder::visitAlloca assumes alloca address space is 0, which is
incorrect for triple amdgcn---amdgiz and causes isel failure.

23c0fc7405 Fix APInt bit size in processDbgDeclares
processDbgDeclares assumes pointer size is the same for different addr spaces.
It uses pointer size for addr space 0 for all pointers, which causes assertion
in stripAndAccumulateInBoundsConstantOffsets for amdgcn---amdgiz since
pointer in addr space 5 has different size than in addr space 0.

This patch fixes that.

710e9b3dae AMDGPU: Replace i64 add/sub lowering
Use VOP3 add/addc like usual.

This has some tradeoffs. Inline immediates fold
a little better, but other constants are worse off.
SIShrinkInstructions could be made smarter to handle
these cases.

This allows us to avoid selecting scalar adds where we
need to track the carry in scc and replace its users.
This makes it easier to use the carryless VALU adds.

0053d0421c [GISel]: Rework legalization algorithm for better elimination of
artifacts along with DCE

Legalization Artifacts are all those insts that are there to make the
type system happy. Currently, the target needs to say all combinations
of extends and truncs are legal and there's no way of verifying that
post legalization, we only have *truly* legal instructions. This patch
changes roughly the legalization algorithm to process all illegal insts
at one go, and then process all truncs/extends that were added to
satisfy the type constraints separately trying to combine trivial cases
until they converge. This has the added benefit that, the target
legalizerinfo can only say which truncs and extends are okay and the
artifact combiner would combine away other exts and truncs.

Updated legalization algorithm to roughly the following pseudo code.

WorkList Insts, Artifacts;
collect_all_insts_and_artifacts(Insts, Artifacts);

do {
  for (Inst in Insts)
         legalizeInstrStep(Inst, Insts, Artifacts);
  for (Artifact in Artifacts)
         tryCombineArtifact(Artifact, Insts, Artifacts);
} while(!Insts.empty());

Also, wrote a simple wrapper equivalent to SetVector, except for
erasing, it avoids moving all elements over by one and instead just
nulls them out.

eb711fee66 CodeGen: Fix TargetLowering::LowerCallTo for sret value type
TargetLowering::LowerCallTo assumes that sret value type corresponds to a
pointer in default address space, which is incorrect, since sret value type
should correspond to a pointer in alloca address space, which may not
be the default address space. This causes assertion for amdgcn target
in amdgiz environment.

This patch fixes that.

bd2cfd038d [AMDGPU] Fix pointer info for lowering load/store for r600 for amdgiz environment
r600 uses dummy pointer info for lowering load/store. Since dummy pointer info
assumes address space 0, this causes isel failure when temporary load/store SDNodes
are generated for amdgiz environment.

Since the offest is not constant, FixedStack pseudo source value cannot be used
to create the pointer info. This patch creates pointer info using llvm undef value.
At least this provides correct address space so that isel can be done correctly.

1a1019d019 AMDGPU: Merge S_BUFFER_LOAD_DWORD_IMM into x2, x4
Summary:
Only constant offsets (*_IMM opcodes) are merged.
It reuses code for LDS load/store merging.
It relies on the scheduler to group loads.

The results are mixed, I think they are mostly positive. Most shaders are
affected, so here are total stats only:

 SGPRS: 2072198 -> 2151462 (3.83 %)
 VGPRS: 1628024 -> 1634612 (0.40 %)
 Spilled SGPRs: 7883 -> 8942 (13.43 %)
 Spilled VGPRs: 97 -> 101 (4.12 %)
 Scratch size: 1488 -> 1492 (0.27 %) dwords per thread
 Code Size: 60222620 -> 52940672 (-12.09 %) bytes
 Max Waves: 374337 -> 373066 (-0.34 %)

There is 13.4% increase in SGPR spilling, DiRT Showdown spills a few more
VGPRs (now 37), but 12% decrease in code size.

These are the new stats for SGPR spilling. We already spill a lot SGPRs,
so it's uncertain whether more spilling will make any difference since
SGPRs are always spilled to VGPRs:

13a223e6e6 [AMDGPU] Fix assertion due to assuming pointer in default addr space is 32 bit
The backend assumes pointer in default addr space is 32 bit, which is not
true for the new addr space mapping and causes assertion for unresolved
functions.

This patch fixes that.

AMDGPULibFunc hardcodes address space values of the old address space mapping,

7bb5f9ead4 DAG: Fix creating select with wrong condition type
This code added in r297930 assumed that it could create
a select with a condition type that is just an integer
bitcast of the selected type. For AMDGPU any vselect is
going to be scalarized (although the vector types are legal),
and all select conditions must be i1 (the same as getSetCCResultType).

This logic doesn't really make sense to me, but there's
never really been a consistent policy in what the select
condition mask type is supposed to be. Try to extend
the logic for skipping the transform for condition types
that aren't setccs. It doesn't seem quite right to me though,
but checking conditions that seem more sensible (like whether the
vselect is going to be expanded) doesn't work since this
seems to depend on that also.

edab757966 MIR: Print the register class or bank in vreg defs
This updates the MIRPrinter to include the regclass when printing
virtual register defs, which is already valid syntax for the
parser. That is, given 64 bit %0 and %1 in a "gpr" regbank,

  %1(s64) = COPY %0(s64)

would now be written as

  %1:gpr(s64) = COPY %0(s64)

While this change alone introduces a bit of redundancy with the
registers block, it allows us to update the tests to be more concise
and understandable and brings us closer to being able to remove the
registers block completely.

Note: We generally only print the class in defs, but there is one
exception. If there are uses without any defs whatsoever, we'll print
the class on all uses. I'm not completely convinced this comes up in
meaningful machine IR, but for now the MIRParser and MachineVerifier
both accept that kind of stuff, so we don't want to have a situation
where we can print something we can't parse.

This converts a large and somewhat arbitrary set of tests to use
update_mir_test_checks. I ran the script on all of the tests I expect
to need to modify for an upcoming mir syntax change and kept the ones
that obviously didn't change the tests in ways that might make it
harder to understand.
