Brian Paul fbd32a04da anv: add a third memory type for LLC configuration
Commit 582bf4d9 turned on write-combining for most (all?) memory
allocations.  This caused a fairly large performance drop in some of
our VMware tests (application traces, such as Windows Metro Paint).

This patch adds a third memory type configuration: DEVICE_LOCAL,
HOST_VISIBLE, HOST_COHERENT.  This is uncached.  Then, in
anv_AllocateMemory() we only use write-combining for this uncached
type.  This memory type is found in the Intel Windows Vulkan driver.
And according to
https://asawicki.info/news_1740_vulkan_memory_types_on_pc_and_how_to_use_them
uncached memory correlates to write-combined memory.

This fixes our performance regression (and actually produced the
fastest ever results for our test suite).

appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
