intel/fs: Add support for bindless texture ops
We add two new texture sources for bindless surface and sampler handles.
Bindless surface handles are expected to be pre-shifted so that the
20-bit surface state table index is in the top 20 bits of the 32-bit
handle. This lets us avoid any extra shifts in the shader. Bindless
sampler handles are 32-byte aligned byte offsets from general state base
address. We use 32-byte aligned instead of 16-byte aligned to avoid
having to use more indirect messages than needed. It means we can't
tightly pack samplers but that's probably not a big deal.

anv: Implement SSBOs bindings with GPU addresses in the descriptor BO
This commit adds a new way for ANV to do SSBO bindings by just passing a
GPU address in through the descriptor buffer and using the A64 messages
to access the GPU address directly. This means that our variable
pointers are now "real" pointers instead of a vec2(BTI, offset) pair.
This carries a few of advantages:
1. It lets us support a virtually unbounded number of SSBO bindings.
2. It lets us implement VK_KHR_shader_atomic_int64 which we couldn't
implement before because those atomic messages are only available
in the bindless A64 form.
3. It's way better than messing around with bindless handles for SSBOs
which is the only other option for VK_EXT_descriptor_indexing.
4. It's more future looking, maybe? At the least, this is what NVIDIA
does (they don't have binding based SSBOs at all). This doesn't a
priori mean it's better, it just means it's probably not terrible.
The big disadvantage, of course, is that we have to start doing our own
bounds checking for robustBufferAccess again have to push in dynamic
offsets.

anv: Make all VkDeviceMemory BOs resident permanently
We spend a lot of time in the driver adding things to hash sets to track
residency. The reality is that a properly built Vulkan app uses large
memory objects and sub-allocates from them. In a typical frame, most of
if not all of those allocations are going to be resident for the entire
frame so we're really not saving ourselves much by tracking fine-grained
residency. Just throwing everything in the validation list does make it
a little bit more expensive inside the kernel to walk the list and
ensure that all our VA is in order. However, without relocations, the
overhead of that is pretty small.
If we ever do run into a memory pressure situation where the fine-
grained residency could even potentially help, we would likely be
swapping one page out to make room for another within the draw call and
performance is totally lost at that point. We're better off swapping
out other apps and just letting ours run a whole frame.

intel/fs: Account for live range lengths in spill costs
The current register allocator has a concept of "spill benefit" which is
based on the number of nodes with which a given node interferes. The
idea is that you want to spill stuff with high interference because
those are the most likely registers to help when spilling. However,
this fails to take into account the length of the live range so the
allocator frequently picks "cheap" (not many uses) registers which are
actually very short lived and so spilling them doesn't help with the
pressure situation.
This commit takes into account the length of the live range to make
long-lived registers more likely to get spilled than short-lived ones.
This encourages the spill chooser to choose slightly larger registers
which will affect a larger area of the program and hopefully we have to
spill fewer of them to get the same reduction in over-all register
pressure.

intel/compiler: split is_partial_write() into two variants
This function is used in two different scenarios that for 32-bit
instructions are the same, but for 16-bit instructions are not.
One scenario is that in which we are working at a SIMD8 register
level and we need to know if a register is fully defined or written.
This is useful, for example, in the context of liveness analysis or
register allocation, where we work with units of registers.
The other scenario is that in which we want to know if an instruction
is writing a full scalar component or just some subset of it. This is
useful, for example, in the context of some optimization passes
like copy propagation.
For 32-bit instructions (or larger), a SIMD8 dispatch will always write
at least a full SIMD8 register (32B) if the write is not partial. The
function is_partial_write() checks this to determine if we have a partial
write. However, when we deal with 16-bit instructions, that logic disables
some optimizations that should be safe. For example, a SIMD8 16-bit MOV will
only update half of a SIMD register, but it is still a complete write of the
variable for a SIMD8 dispatch, so we should not prevent copy propagation in
this scenario because we don't write all 32 bytes in the SIMD register
or because the write starts at offset 16B (wehere we pack components Y or
W of 16-bit vectors).
This is a problem for SIMD8 executions (VS, TCS, TES, GS) of 16-bit
instructions, which lose a number of optimizations because of this, most
important of which is copy-propagation.
This patch splits is_partial_write() into is_partial_reg_write(), which
represents the current is_partial_write(), useful for things like
liveness analysis, and is_partial_var_write(), which considers
the dispatch size to check if we are writing a full variable (rather
than a full register) to decide if the write is partial or not, which
is what we really want in many optimization passes.
Then the patch goes on and rewrites all uses of is_partial_write() to use
one or the other version. Specifically, we use is_partial_var_write()
in the following places: copy propagation, cmod propagation, common
subexpression elimination, saturate propagation and sel peephole.
Notice that the semantics of is_partial_var_write() exactly match the
current implementation of is_partial_write() for anything that is
32-bit or larger, so no changes are expected for 32-bit instructions.
Tested against ~5000 tests involving 16-bit instructions in CTS produced
the following changes in instruction counts:
Patched | Master | % |
================================================
SIMD8 | 621,900 | 706,721 | -12.00% |
================================================
SIMD16 | 93,252 | 93,252 | 0.00% |
================================================
As expected, the change only affects SIMD8 dispatches.

Empirical testing shows that gen8 has a bug where MAD instructions with

This scenario usually happened in SIMD8 executions, where we used to
pack vector components Y and W in the second half of SIMD registers
(therefore, with a 16B offset). It looks like we are not currently doing
