Jay Foad bba37e89a5 [AMDGPU] Allow abs/neg source modifiers on v_cndmask_b32
Summary:
D59191 added support for these modifiers in the assembler and
disassembler. This patch just teaches instruction selection that it can
use them.

Stanislav Mekhanoshin 465a1ff193 [AMDGPU] Eliminate SGPR to VGPR copy when possible
SGPRs are generally cheaper, so try to use them over VGPRs.

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.

Matt Arsenault 5d8eb25e78 AMDGPU: Use unsigned compare for eq/ne
For some reason there are both of these available, except
for scalar 64-bit compares which only has u64. I'm not sure
why there are both (I'm guessing it's for the one bit inputs we
don't use), but for consistency always using the
unsigned one.

Matt Arsenault fa5f767a38 AMDGPU: Improve splitting 64-bit bit ops by constants
This addresses a TODO to handle operations besides and. This
also starts eliminating no-op operations with a constant that
can emerge later.

Artem Tamazov 135487767b [AMDGPU][llvm-mc] v_cndmask_b32: src2 is mandatory; do not enforce VOP2 when src2 == VCC.
Another step for unification llvm assembler/disassembler with sp3.
Besides, CodeGen output is a bit improved, thus changes in CodeGen tests.
Assembler/Disassembler tests updated/added.

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 5e0bdb8b95 AMDGPU: Implement {{s|u}}int_to_fp i64 -> f32
The old lowering for uint_to_fp failed opencl conformance.
It might be OK for fast math mode, but I'm not sure.
