This was the actual cause of GPU hangs fixed by 0fdd531457 ("radv:
Fix pipeline cache locking issues"), since multiple threads would end
up trying to create the variants for a single entry.
Now that we're locking around the whole of this function, this isn't
really necessary (we either create all or none of the variants), but
fix this anyway in case things change later.

Need to lock around the whole process of retrieving cached shaders, and
around GetPipelineCacheData.
This fixes GPU hangs observed when creating multiple pipelines in
parallel, which appeared to be due to invalid shader code being pulled
from the cache.

If the app provided in-memory pipeline cache doesn't yet contain
what we are looking for, or it doesn't provide one at all then we
fallback to the on-disk cache.

I tested this 10 times with
./deqp-vk --deqp-case=dEQP-VK.texture.filtering.3d.formats.r4g4b4a4*
and one full run of CTS, seems the issue is gone.
Also reduces CTS runtime by 30% or so.

Currently if table_size is 0, it's falling through to:
unreachable("hash table should never be full");
But table_size can be 0 when RADV_DEBUG=nocache is set, or when the
table allocation fails (which is not considered an error).

This reduces the number of BOs that we need for the BO lists during
a submission.
Currently uses a fairly simple linear search for finding free space,
that could eventually be improved to a binary tree, which with some
per-node info could make a check for space O(1) and finding it O(log n),
in the number of buffers in that slab.

Rather than having an extra memory allocation [that we currently do not
and act accordingly] just make the API take an pointer to a stack
allocated instance.
This and follow-up steps will effectively make the _mesa_sha1_foo simple

Less IFETCH latency on misses. Shader code is write once read many,
so GTT doesn't make much sense anyway.
If it turns out to fragment the CPU visible VRAM too much, we can upload with SDMA.

This requires llvm 3.9 and is in no way considered
a conformant vulkan implementation. It can run a number
of vulkan applications, and supports all GPUs using
the amdgpu kernel driver.
