Summary:
Prior to GCN3 s_load_dword offsets are in dwords rather than bytes.
Thus the scratch buffer descriptor offset must be adjusted for pre-GCN3 ASICs.

Summary:
For OS type AMDPAL, the scratch descriptor is loaded from offset 0 of
the GIT, whose 32 bit pointer is in s0 (s8 for gfx9 merged shaders).
This commit fixes that to use offset 0x10 instead of offset 0 for a
compute shader, per the PAL ABI spec.
V2: Ensure s0 (s8 for gfx9 merged shader) is marked live-in when loading
scratch descriptor from GIT.

This reverts commit 0daf86291d3aa04d3cc280cd0ef24abdb0174981.
It was causing an assert in test/CodeGen/AMDGPU/amdpal.ll only on a
release-with-asserts build. I will resubmit the change when I have fixed
that.

Summary:
Now we generate PAL metadata for the amdpal os type, there is no need to
generate the .AMDGPU.config section.

This requires corresponding clang change.

Summary:
Added support for scratch (including spilling) for OS type amdpal:
generates code to set up the scratch descriptor if it is needed.
With amdpal, the scratch resource descriptor is loaded from offset 0 of
the global information table. The low 32 bits of the address of the
global information table is passed in s0.
Added amdgpu-git-ptr-high function attribute to hard-wire the high 32
bits of the address of the global information table. If the function
attribute is not specified, or is 0xffffffff, then the backend generates
code to use the high 32 bits of pc.
The documentation for the AMDPAL ABI will be added in a later commit.

Summary:
This operating system type represents the AMDGPU PAL runtime, and will
be required by the AMDGPU backend in order to generate correct code for
this runtime.
Currently it generates the same code as not specifying an OS at all.
That will change in future commits.
Patch from Tim Corringham.
