blorp: Use normalized coordinates on Gen6

Apparently, the sampler has some sort of precision issues for
non-normalized texture coordinates with linear filtering.  This caused
some small precision issues in scaled blits.  Work around this by using
normalized coordinates.  There is some extra work necessary because Gen6
uses TEX (instead of TXF) for some multisample resolve blits.

llvmpipe: initialize default fb correctly in setup

If lp_setup_bind_framebuffer() is never called, then setup fb x1/y1 was not
correctly initialized. This can happen if there's never a fb set - both
cso and llvmpipe would consider setting this with no cbufs and no zsbuf a
redundant change and therefore it would never get set.
We rely on this setup fb rect being initialized correctly for the tri intersect
tests, throwing away tris which don't intersect. Not initializing it meant
we'd then say it intersected, and we'd try to bin that despite that we have
no actual tiles to bin it to, leading to assertion failures (pretty harmless
since tile 0/0 always exists nevertheless as tiles are statically allocated,
albeit that should change at some point).
(Note probably not an issue with gl state tracker)

i965/miptree: Rework aux enabling

This commit replaces the complex and confusing set of disable flags with
two fairly straightforward fields which describe the intended auxiliary
surface usage and whether or not the miptree supports fast clears.
Right now, supports_fast_clear can be entirely derived from aux_usage
but that will not always be the case.

This commit makes functional changes.  One of these changes is that it
re-enables multisampled fast-clears which were accidentally disabled in
cec30a666930ddb8476a9452a89364a24979ff62 around a year ago.  Fixing this
improves the SynMark v7 DeferredAA test by around ~3% on some gen9
hardware.  This commit also gets us closer to enabling CCS_E for
window-system buffers which are Y-tiled.

i965: Clamp clear colors to the representable range

Starting with Sky Lake, we can clear to arbitrary floats or integers.
Unfortunately, the hardware isn't particularly smart when it comes
sampling from that clear color.  If the clear color is out of range for
the surface format, it will happily return whatever we put in the
surface state packet unmodified.  In order to avoid returning bogus
values for surfaces with a limited range, we need to do some clamping.

i965/miptree: Delete the layered rendering resolve
