clover: Update OpenCL headers to version 1.2 from Khronos.

The C++ headers are *not* updated because they rely on CL 1.2 APIs
that we do not implement yet when the core CL 1.2 headers are present.

clover: Stub implementation of CL 1.2 sub-devices.

The implementation is basically a NOP but it conforms with OpenCL 1.2.

[ Francisco Jerez: Initialize property return buffer for
  CL_DEVICE_PARTITION_PROPERTIES, CL_DEVICE_PARTITION_TYPE,
  CL_DEVICE_PARTITION_AFFINITY_DOMAIN, and make the latter a scalar
  rather than a vector.  Some clean-up and code style fixes. ]

i965: Fix a few base addresses on Broadwell.

We intended to set these 64-bit addresses to 0, and set the enable bit.
But, I accidentally placed the DWord with the high bits first, when it
should have been second.

This generally worked out, by luck - presumably General State Base
Address is initially zero, and ends up remaining that way in our
contexts since we bungled the "modify enable" bit.

v2: Fix MOCS shift on GSBA.  It should be 4, and I had 2.

translate_sse: Use the correct buffer index in this fast path.

It is possible that there are multiple input buffers but only one is
relevant for translation. Then there will be only a single translation
group, which might need to source data from a buffer index != 0.

Fixes wrong vertex shader inputs as observed while debugging with an
application and driver combination that requires translation of a
vertex attribute in a non-trivial set of attributes and input buffers.
