Instead of making LMEM the special case, unify the two paths by setting
up a fake drm_i915_query_memory_regions struct and filling it out based
on OS queries. The important functional change here is that we now pass
system memory through the same GTT size and 3/4 filter that we were
using with the OS queries. This should make behavior consistent on
integrated GPUs regardless of whether or not we have the memory region
query API.

There are two problems with the current architecture.
In OpenGL, the id is supposed to be a unique identifier for a particular
log source. This is done so that applications can (theoretically)
filter particular log messages. The debug callback infrastructure in
Mesa assigns a uniqe value when a value of 0 is passed in. This causes
the id to get set once to a unique value for each message.
By passing a stack variable that is initialized to 0 on every call,
every time the same message is logged, it will have a different id.
This isn't great, but it's also not catastrophic.
When threaded shader compiles are used, the id *pointer* is saved and
dereferenced at a possibly much later time on a possibly different
thread. This causes one thread to access the stack from a different
thread... and that stack frame might not be valid any more. :(
I have not observed any crashes related to this particular issue.

Sync object for i915 support has been in upstream Linux since 4.14 which
is 3.5 years old at this point and, as far as we can tell, it also
exists in all the ChromeOS kernels. Assuming it allows us to drop some
of our more gnarly synchronization fall-back paths.
At the time of merge, ChromeOS was on the following kernels:
- kernel 3.18: SKL
- kernel 4.4: BYT, KBL, APL
- Kernel 4.14: BDW, GLK
All of the pre-4.14 kernels have had syncobj support back-ported.

This is distinct form max_cs_threads because it also encodes
restrictions about the way we use GPGPU/COMPUTE_WALKER. This gets rid
of the MIN2(64, devinfo->max_cs_threads) we have scattered all over the
driver and puts it in a central place.

Cherryview is weird in that the actual limits we can expose through GL
are dependent on fusing information which is only obtainable at runtime.
The same PCI ID may have different configurations with different maximum
CS thread counts. We currently handle this in i965 and ANV by doing the
calculation in the driver.
This dates back to when intel_device_info was computed from the PCI ID.
Now that we have get_device_info_from_fd, we can move the CHV stuff
there and get it out of the driver. This fixes CHV thread counts on
crocus as well.

This has two steps. First, for each range we look at the memory object
and see if it actually needs flushing before we start throwing CLFLUSH
instructions. Second, we look at the whole list of types on device
initialization and decide whether or not we need CLFLUSH at all. The
first part should speed up atom chips a bit since we're currently
CLFLUSHing everything even when we don't need to. The second isn't
needed on most of today's parts because we base it on !has_llc but it is
needed for discrete parts. It's also over-all cleaner.

acquire a reference on the AHB. So if we layer the exportable allocation
on top of AHB allocation and AHB import, we must release an AHB
reference to avoid leak.
