Matt Arsenault 296b849163 AMDGPU: Set flat_scratch from flat_scratch_init reg
This was hardcoded to the static private size, but this
would be missing the offset and additional size for someday
when we have dynamic sizing.

Also stops always initializing flat_scratch even when unused.

In the future we should stop emitting this unless flat instructions
are used to access private memory. For example this will initialize
it almost always on VI because flat is used for global access.

Tom Stellard 9a197676b1 AMDGPU/SI: Fold operands through REG_SEQUENCE instructions
Summary:
This helps mostly when we use add instructions for address calculations
that contain immediates.

Matt Arsenault 711b390a7c AMDGPU: Assume SMRD access for constant address space
Since r243294 these are selected to SMRD and
moved later if required.

Tom Stellard 70580f83cc AMDGPU/SI: Add VI patterns to select FLAT instructions for global memory ops
Summary:
The MUBUF addr64 bit has been removed on VI, so we must use FLAT
instructions when the pointer is stored in VGPRs.
