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.

Konstantin Zhuravlyov 0a1a7b6b23 Revert "AMDGPU: Enable ConstrainCopy DAG mutation"
This reverts commit r287146.

This breaks few conformance tests.

Matt Arsenault 3b36bb1d87 AMDGPU: Enable ConstrainCopy DAG mutation
This fixes a probably unintended divergence from the default
scheduler behavior.

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.

Matt Arsenault 124384f08d AMDGPU: Fix immediate folding logic when shrinking instructions
If the literal is being folded into src0, it doesn't matter
if it's an SGPR because it's being replaced with the literal.

Also fixes initially selecting 32-bit versions of some instructions
which also confused commuting.

Matt Arsenault 71fa1f375e AMDGPU: Fix a few slightly broken tests
Fix minor bugs and uses of undef which break when
pointer related optimization passes are run.

Matthias Braun 97d0ffbe06 ScheduleDAGInstrs: Rework schedule graph builder.
Re-comitting with a change that avoids undefined uses getting put into
the VRegUses list.

The new algorithm remembers the uses encountered while walking backwards
until a matching def is found. Contrary to the previous version this:
- Works without LiveIntervals being available
- Allows to increase the precision to subregisters/lanemasks
  (not used for now)

The changes in the AMDGPU tests are necessary because the R600 scheduler
is not stable with respect to the order of nodes in the ready queues.

Matthias Braun 2fd672a221 Revert "ScheduleDAGInstrs: Rework schedule graph builder."
This works mostly fine but breaks some stage 1 builders when compiling
compiler-rt on i386. Revert for further investigation as I can't see an
obvious cause/fix.

This reverts commit r254577.
