The Vulkan spec does not specify that the free function provided to
CreateInstance must handle NULL properly so we do it in the wrapper. If
this ever changes in the spec, we can delete the extra 2 lines.
While updating vkDestroyObject, I discovered that vkDestroyPass reliably
crashes. That hasn't been an issue yet, though, because it is never
called.
In vkCreateRenderPass:
- Don't allocate empty attachment arrays.
- Ensure that pointers to empty attachment arrays are NULL.
- Store VkRenderPassCreateInfo::subpassCount as
anv_render_pass::subpass_count.
In vkDestroyRenderPass:
- Fix loop bounds: s/attachment_count/subpass_count/
- Don't call anv_device_free on null pointers.
Along with fixing the type of pitch parameter, patch also changes
the types of few local variables and function return type.
Warnings fixed are:
intel_mipmap_tree.c:671:7: warning: passing argument 3 of
'intel_get_yf_ys_bo_size' from incompatible pointer type
intel_mipmap_tree.c:563:1: note: expected 'uint64_t *' but
argument is of type 'long unsigned int *'

Previously OUT_BATCH was just a macro around an inline function which
does
brw->batch.map[brw->batch.used++] = dword;
When making consecutive calls to intel_batchbuffer_emit_dword() the
compiler isn't able to recognize that we're writing consecutive memory
locations or that it doesn't need to write batch.used back to memory
each time.
We can avoid both of these problems by making a local pointer to the
next location in the batch in BEGIN_BATCH().

So that everything writing to the batch between BEGIN_BATCH() and
ADVANCE_BATCH() goes through OUT_BATCH.
Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
BEGIN_BATCH() and ADVANCE_BATCH() will contain "do {" and "} while (0)"
respectively to allow declaring local variables used by intervening
OUT_BATCH macros. As such, BEGIN_BATCH() and ADVANCE_BATCH() need to be
in the same control flow.

This field should always be set for gen8. In the bdw PRM, Volume 2d:
Command Reference: Structures under INTERFACE_DESCRIPTOR_DATA, DWORD
6, Bits 9:0, Number of Threads in GPGPU Thread Group:
"This field should not be set to 0 even if the barrier is disabled,
since an accurate value is needed for proper pre-emption."
In the HSW PRM, the it doesn't mention that it must always be set, but
it should not hurt.
