i965/clear: Quantize the depth clear value based on the format

In f9fd976e8adba733b08d we changed the clear value to be stored as an
isl_color_value.  This had the side-effect same clear value check is now
happening directly between the f32[0] field of the isl_color_value and
ctx->Depth.Clear.  This isn't what we want for two reasons.  One is that
the comparison happens in floating point even for Z16 and Z24 formats.
Worse than that, ctx->Depth.Clear is a double so, even for 32-bit float
formats, we were comparing as doubles and not floats.  This means that
the test basically always fails for anything other than 0.0f and 1.0f.
This caused a slight performance regression in Lightsmark 2008 because
it was using a depth clear value of 0.999 which can't be stored in a
32-bit float so we were doing unneeded resolves.

Previously the brw_inst{,_set}_{dst,src0,src1}_reg_type() functions

themselves used to be the hardware format!) with bad results.

With that functionality now available with the hw_ versions (see

BRW_REGISTER_TYPE_* enums and convert into the hardware format and vice
versa. To do the conversion we also have to provide the file.

Note the asymmetry between the two functions: the new getter reads the

i965/bufmgr: s/BO_ALLOC_FOR_RENDER/BO_ALLOC_BUSY/

"Alloc for render" is a terrible name for a flag because it means
basically nothing.  What the flag really does is allocate a busy BO
which someone theorized at one point in time would be more efficient if
you're planning to immediately render to it.  If the flag really means
"alloc a busy BO" we should just call it that.

i965/tex: Don't pass samples to miptree_create_for_teximage

In 76e2f390f9863a35, when Topi switched num_samples from 0 to 1 for
single-sampled, he accidentally switched the last parameter in the call
to miptree_create_for_teximage from 0 to 1 thinking it was num_samples
when it was actually layout_flags.  Switching from 0 to 1 added the
MIPTREE_LAYOUT_ACCELERATED_UPLOAD flag which causes us to allocate a
busy BO instead of an idle one.  This caused the subsequent CPU upload
to consistently stall.  The end result was a 15% performance drop in the
SynMark v7 DrvRes microbenchmark.  This restores the old behavior and
fixes the performance regression.

i965: Use ISL for emitting null surface states.

We handle the Sandybridge multisampled 2D surface hack here, rather
than in ISL, because it requires allocating a BO, and is kind of messy.

isl: Add a null surface fill function.

ISL already offers functions to fill out most kinds of SURFACE_STATE,

Null surfaces are simple, so we can just take the dimensions, rather
