Stores failed to decode at all since they didn't have a
DecoderNamespace set. Loads worked, but did not change
the register width displayed to match the numbmer of
enabled channels.
The number of printed registers for vaddr is still wrong,
but I don't think that's encoded in the instruction so
there's not much we can do about that.
Image atomics are still broken. MIMG is the same
encoding for SI/VI, but the image atomic classes
are split up into encoding specific versions unlike
every other MIMG instruction. They have isAsmParserOnly
set on them for some reason. dmask is also special for
these, so we probably should not have it as an explicit
operand as it is now.

Intrinsic already existed for llvm.SI.tbuffer.store
Needed tbuffer.load and also re-implementing the intrinsic as llvm.amdgcn.tbuffer.*
Added CodeGen tests for the 2 new variants added.
Left the original llvm.SI.tbuffer.store implementation to avoid issues with existing code

A new Gfx9 dasm test added with approx 29000 cases.
Existing tests extended by (approx.):
* Gfx7 asm: 5000 test cases
* Gfx8 asm: 5000 test cases
* Gfx9 asm: 14400 test cases
* Gfx8 dasm: 5200 test cases

We don't use it and it was removed in gfx9, and the encoding
bit repurposed.
Additionally actually using it requires changing the output register
class, which wasn't done anyway.

The unused dummy src2_modifiers is missing, so it crashes
when trying to print it.
I tried to fully remove src2_modifiers, but there are some
irritations in the places where it is converted to mad since
it starts to require modifying use lists while iterating over
them.

- corrected DS_GWS_* opcodes (see VI_Shader_Programming#16.pdf for detailed description)
- address operand is not used
- several opcodes have data operand
- all opcodes have offset modifier
- DS_AND_SRC2_B32: corrected typo in mnemo
- DS_WRAP_RTN_F32 replaced with DS_WRAP_RTN_B32
- added CI/VI opcodes:
- DS_CONDXCHG32_RTN_B64
- DS_GWS_SEMA_RELEASE_ALL
- added VI opcodes:
- DS_CONSUME
- DS_APPEND
- DS_ORDERED_COUNT

Reason: broke ASAN bots with a global buffer overflow.

Each test contains 20-30K test cases but takes only several (from 4 to 10)
seconds to complete on average machine. The tests cover the majority of
AMDGPU Gfx7/Gfx8 instructions, including many dark corners, and intended
to quickly find out if something is broken.

Summary: Real instruction should copy constraints from real instruction. This allows auto-generated disassembler to correctly process tied operands.

Since 32-bit instructions with 32-bit input immediate behavior
are used to materialize 16-bit constants in 32-bit registers
for 16-bit instructions, determining the legality based
on the size is incorrect. Change operands to have the size
specified in the type.
Also adds a workaround for a disassembler bug that
produces an immediate MCOperand for an operand that
is supposed to be OPERAND_REGISTER.
The assembler appears to accept out of bounds immediates and
truncates them, but this seems to be an issue for 32-bit
already.

Fixes Bug 30808.
Note that passing subtarget information to predicates seems too complicated, so gfx8-specific def smrd_offset_20 introduced.
Old gfx6/7-specific def renamed to smrd_offset_8 for clarity.
Lit tests updated.
