Matt Arsenault db7c6a8731 AMDGPU: Start selecting flat instruction offsets

Matt Arsenault 3dbeefa978 AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel
Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.

Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

Matt Arsenault 7aad8fd8f4 Enable FeatureFlatForGlobal on Volcanic Islands
This switches to the workaround that HSA defaults to
for the mesa path.

This should be applied to the 4.0 branch.

Tom Stellard f8e6eaff6e AMDGPU/SI: Don't emit multi-dword flat memory ops when they might access scratch
Summary:
A single flat memory operations that might access the scratch buffer
can only access MaxPrivateElementSize bytes.

Tom Stellard 9daed22b04 AMDGPU/SI: Remove unnecessary run lines from test
Summary:
This test had run lines disabling/enabling the promote alloca pass, but
enabling/disabling promote alloca had no impact on the output.

Tom Stellard 46937ca4e7 [AMDGPU] Assembler: Swap operands of flat_store instructions to match AMD assembler
Historically, AMD internal sp3 assembler has flat_store* addr, data
format. To match existing code and to enable reuse, change LLVM
definitions to match.  Also update MC and CodeGen tests.

Matt Arsenault 2aed6ca1d3 AMDGPU: Switch barrier intrinsics to using convergent
noduplicate prevents unrolling of small loops that happen to have
barriers in them. If a loop has a barrier in it, it is OK to duplicate
it for the unroll.

Nicolai Haehnle dd58705af6 AMDGPU: fix overlapping copies in copyPhysReg
Summary:
When copying aggregate registers within the same register class, there may
be an overlap between source and destination that forces us to do the copy
backwards.

Do the simplest possible thing that guarantees the correct order of moves
when there are overlaps, and does whatever when there is no overlap. (The
last part forces some trivial adjustments to test cases.)

Together with r255906, this fixes a VM fault in Unreal Elemental Demo.

While at it, change the generation of kill and def flags to something that
looks more reasonable. This method is used very late during compilation, so
it probably doesn't matter in practice, and to be honest, I don't know if
this change is actually correct because the semantics in connection with
aggregate registers vs. sub-registers are not clear to me.
