i965: Fix INTEL_DEBUG=shader_time for SIMD8 VS (and GS).

We were incorrectly attributing VS time to FS8 on Gen8+, which now use
fs_visitor for vertex shaders.

We don't hit this for geometry shaders yet, but we may as well add
support now - the fix is obvious, and we'll just forget later.

i965/fs: Use inst->eot rather than opcodes in register allocation.

Previously, we special cased FB writes and URB writes in the register

i965/fs: Delete is_last_send(); just check inst->eot.

This helper function basically just checks inst->eot, but also asserts
that only opcodes we expect to terminate threads have EOT set.  As far
as I'm aware, we've never had such a bug.

Removing it means that we don't have to extend the list for new opcodes.
Cherryview and Skylake introduce an optimization where sampler messages
can have EOT set; scalar GS/HS/DS will likely introduce new opcodes as
well.

gallium/targets/d3dadapter9: Fix device detection for render-nodes

When on a render node the unique ioctl doesn't work.

This patch drops the code to detect the device, which relied
on an ioctl, and replaces it by the mesa loader function.
The mesa loader function is more complete and won't fail for render-nodes.

Alternatively we could also have used the pipe cap to
