i965: Allow a per gen timebase scale factor
Prior to Skylake the Gen HW timestamps were driven by a 12.5MHz clock
with the convenient property of being able to scale by an integer (80)
to nanosecond units.
For Skylake the frequency is 12MHz or a scale factor of 83.333333
This updates gen_device_info to track a floating point timebase_scale
factor and makes corresponding _queryobj.c changes to no longer assume a
scale factor of 80 works across all gens.
Although the gen6_ code could have been been left alone, the changes
keep the code more comparable, and it now shares a few utility functions
for scaling raw timestamps and calculating deltas. The utility for
calculating deltas takes into account 32 or 36bit overflow depending on
the current kernel version.
Note: this leaves the timestamp handling of ARB_query_buffer_object
untouched, which continues to use an incorrect scale of 80 on Skylake
for now. This is more awkward to solve since the scaling is currently
done using a very limited uint64 ALU available to the command parser
that doesn't support multiply or divide where it's already taking a
large number of instructions just to effectively multiple by 80.
This fixes piglit arb_timer_query-timestamp-get on Skylake

avoid crashes due to access to memory that we failed to allocate previously.
The strategy used to do this is to track the first error ocurred while
recording a command buffer in the batch associated with it. We use the
batch to track this information because the command buffer may not be
visible to all parts of the driver that can produce errors we need to be
aware of (such as allocation failures during batch emissions).
Later patches will use this error information to guard parts of the driver
that may not be safe to execute.
v2: Move the field from the command buffer to the batch so we can track
errors from batch emissions (Jason)
v3: Registering errors in the command buffer's batch during
anv_create_cmd_buffer() is unnecessary, since the command buffer
is freed at the end of the function in that case (Topi)

gallium/tgsi: Treat UCMP sources as floats to match the GLSL-to-TGSI pass expectations.
Currently the GLSL-to-TGSI translation pass assumes it can use
floating point source modifiers on the UCMP instruction. See the bug
report linked below for an example where an unrelated change in the
GLSL built-in lowering code for atan2 (
e9ffd12827ac11a2d2002a42fa8eb1)
caused the generation of floating-point ir_unop_neg instructions
followed by ir_triop_csel, which is translated into UCMP with a negate
modifier on back-ends with native integer support.
Allowing floating-point source modifiers on an integer instruction
seems like rather dubious design for a transport IR, since the same
semantics could be represented as a sequence of MOV+UCMP instructions
instead, but supposedly this matches the expectations of TGSI
back-ends other than tgsi_exec, and the expectations of the DX10 API.
I take no responsibility for future headaches caused by this
inconsistency.

the above-mentioned glsl front-end commit. Even though the commit
that triggered the regression doesn't seem to have made it to any

see any reason why the bug couldn't have been reproduced before that

The idea behind modifiers like this is that the user of GBM will have
some mechanism to query what properties the hardware supports for its BO

the DRI implementation can create an image with the appropriate
attributes.
A getter() will be added later so that the user GBM will be able to
query what modifier should be used.
Only in surface creation, the modifiers are stored until the BO is
actually allocated. In regular buffer allocation, the correct modifier
can (will be, in future patches be chosen at creation time.
