[AMDGPU] GFX11: automatically release VGPRs at the end of the shader
GFX11 has a new message type MSG_DEALLOC_VGPRS which can be used to
release a shader's VGPRs. Sending this at the end of a shader (just
before the s_endpgm) can help overall system performance in cases where
the s_endpgm would have to wait for outstanding VMEM stores to complete
before releasing the VGPRs.

[AMDGPU] GFX11 CodeGen support for MIMG instructions
This includes:
- New llvm.amdgcn.image.msaa.load.* intrinsics
- NSA changes, because MIMG-NSA is now limited to 3 dwords
- Split CD forms of IMAGE_SAMPLE instructions out into separate
test files since they are no longer supported in GFX11

[AMDGPU] Insert waitcnt after returning from call
When memory operations are outstanding on function calls, either the
caller or the callee can insert a waitcnt to ensure that all reads are
finished
[AMDGPU] Insert waitcnt after returning from call
When memory operations are outstanding on function calls, either the
caller or the callee can insert a waitcnt to ensure that all reads are
finished.
Calls need some time to be executed, so if the callee inserts the
waitcnt, filling the instruction buffer and waiting for memory will be
interleaved, hiding some latency. This comes at the cost of having a
waitcnt inside functions that may not be needed as no memory operations
are outstanding.
For function calls, this is already implemented. The same principal
applies to returns: If the caller inserts a waitcnt after the call, the
callee does not have to wait and the return and memory operation can be
run in parallel.
This commit implements waiting in the caller after returning from a
function call.
