Ryan Taylor 29257eb76c [AMDGPU] Increases available SGPR for Calling Convention
Summary:
SGPR in CC can be either hw initialized or set by other chained shaders
and so this increases the SGPR count availalbe to CC to 105.

Tim Renouf 033f99a2e5 [AMDGPU] Added v5i32 and v5f32 register classes
They are not used by anything yet, but a subsequent commit will start
using them for image ops that return 5 dwords.

Tim Renouf 361b5b2193 [AMDGPU] Support for v3i32/v3f32
Added support for dwordx3 for most load/store types, but not DS, and not
intrinsics yet.

SI (gfx6) does not have dwordx3 instructions, so they are not enabled
there.

Some of this patch is from Matt Arsenault, also of AMD.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Matt Arsenault 55ab9213d3 AMDGPU: Partially fix handling of packed amdgpu_ps arguments
Fixes annoying limitations when writing tests.
Also remove more leftover code for manually scalarizing arguments
and return values.

Tom Stellard 5bfbae5cb1 AMDGPU: Refactor Subtarget classes
Summary:
This is a follow-up to r335942.
- Merge SISubtarget into AMDGPUSubtarget and rename to GCNSubtarget
- Rename AMDGPUCommonSubtarget to AMDGPUSubtarget
- Merge R600Subtarget::Generation and GCNSubtarget::Generation into
  AMDGPUSubtarget::Generation.

Matt Arsenault 29f303799b AMDGPU/GlobalISel: Implement custom kernel arg lowering
Avoid using allocateKernArg / AssignFn. We do not want any
of the type splitting properties of normal calling convention
lowering.

For now at least this exists alongside the IR argument lowering
pass. This is necessary to handle struct padding correctly while
some arguments are still skipped by the IR argument lowering
pass.

Tom Stellard c5a154db48 AMDGPU: Separate R600 and GCN TableGen files
Summary:
We now have two sets of generated TableGen files, one for R600 and one
for GCN, so each sub-target now has its own tables of instructions,
registers, ISel patterns, etc.  This should help reduce compile time
since each sub-target now only has to consider information that
is specific to itself.  This will also help prevent the R600
sub-target from slowing down new features for GCN, like disassembler
support, GlobalISel, etc.

Matt Arsenault 02dc7e19e2 AMDGPU: Make v4i16/v4f16 legal
Some image loads return these, and it's awkward working
around them not being legal.

Matt Arsenault b62a4eb524 AMDGPU: Initial implementation of calls
Includes a hack to fix the type selected for
the GlobalAddress of the function, which will be
fixed by changing the default datalayout to use
generic pointers for 0.

Matt Arsenault 2b1f9aa577 AMDGPU: Start defining a calling convention
Partially implement callee-side for arguments and return values.
byval doesn't work properly, and most likely sret or other on-stack

Don't use AllocateStack because kernel arguments have nothing
to do with the stack. The ensureMaxAlignment call was still

Marek Olsak 8a0f335ad6 AMDGPU/SI: Add support for non-void functions
Summary:
Return values can be stored in SGPRs (i32) and VGPRs (f32).

This will be used by functions which expect some bytecode or other binary to
be appended at the end. It allows defining in which registers the return
values will be stored.

v2: don't do this for compute shaders
