i965: Implement fast color clears using meta operations

This patch uses the infrastructure put in place by previous patches
to implement fast color clears and replicated color clears in terms of
meta operations.

This works all the way back to gen7 where fast clear was introduced and
adds support for fast clear on gen8.  It replaces the blorp path
completely and improves on a few cases.  Layered clears are now done
using instanced rendering and multiple render-target clears use a
MRT shader with rep16 writes.

i965: Add optimization pass to let us use the replicate data message

The data port has a SIMD16 'replicate data' message, which lets us write
the same color for all 16 pixels by sending the four floats in the
lower half of a register instead of sending 4 times 16 identical
component values in 8 registers.

The message comes with a lot of restrictions and could be made generally
useful by recognizing when those restriction are satisfied.  For now,
this lets us enable the optimization when we know it's safe, but we don't
enable it by default.  The optimization works for simple color clear shaders
only, but does recognized and support multiple render targets.

mesa: Use _mesa_lock_context_textures in _mesa_GetTexParameterfv()

GetTexParamterfv() doesnt change texture state, so instead of
_mesa_lock_texture() we can use _mesa_lock_context_textures(),
which doesn't increase the texture stamp.  With this change,
_mesa_update_state_locked() is now only called from under
_mesa_lock_context_textures(), which is right thing to do.  Right now
it's the same mutex, but if we made texture locking more fine grained
locking one day, just locking one texture here would be wrong.

This all ignores the fact that texture locking seem a bit
flaky and broken, but we're trying to not blatantly make it worse.

This change allows us to reliably unlock the context textures in the
dd::UpdateState callback as is necessary for meta color resolves.
