st/nine: Hack to generate resource if it doesn't exist when getting view
Buffers in the MANAGED pool are supposed to have the content in a ram buffer,
a copy in VRAM if there is enough memory (driver manages memory and decide when
to delete the buffer in VRAM).
This is not implemented properly in nine, and a VRAM copy is going to be created
when the RAM memory is filled, and the VRAM copy will get synced with the RAM
memory updates.
Due to some issues (in the implementation or in app logic), it can happen
we try to create a sampler view of the resource while we haven't created the
VRAM resource. This hack creates the resource when we hit this case, which prevents
crashing, but doesn't help with the resource content.
This fixes several games crashing at launch.

i965: Work around mysterious Gen4 GPU hangs with minimal state changes.
Gen4 hardware appears to GPU hang frequently when using Chromium, and
also when running 'glmark2 -b ideas'. Most of the error states contain
3DPRIMITIVE commands in quick succession, with very few state packets
between them - usually VERTEX_BUFFERS/ELEMENTS and CONSTANT_BUFFER.
I trimmed an apitrace of the glmark2 hang down to two draw calls with a
glUniformMatrix4fv call between the two. Either draw by itself works
fine, but together, they hang the GPU. Removing the glUniform call
makes the hangs disappear. In the hardware state, this translates to
removing the CONSTANT_BUFFER packet between the two 3DPRIMITIVE packets.
Flushing before emitting CONSTANT_BUFFER packets also appears to make
the hangs disappear. I observed a slowdown in glxgears by doing it all
the time, so I've chosen to only do it when BRW_NEW_BATCH and
BRW_NEW_PSP are unset (i.e. we haven't done a CS_URB_STATE change or
already flushed the whole pipeline).
I'd much rather understand the problem, but at this point, I don't see
how we'd ever be able to track it down further. We have no real tools,
and the hardware people moved on years ago. I've analyzed 20+ error
states and read every scrap of documentation I could find.

i965/nir: Replace fs_reg(GRF, virtual_grf_alloc(...)) with vgrf(...).
brw_fs_nir.cpp creates almost all of its registers via:
fs_reg reg = fs_reg(GRF, virtual_grf_alloc(num_components));
When we add SIMD16 support, we'll need to set reg->width = 16 and
double the VGRF size...on pretty much every VGRF it allocates.
This patch replaces that pattern with a new "vgrf" helper method:
fs_reg reg = vgrf(num_components);
The new function correctly takes reg_width into account. For now,
reg_width is always 1, so this should have no functional change.
v2: Just make vgrf() account for reg_width right away, rather than
changing the behavior in the next patch.
v3: Replace one last virtual_grf_alloc I missed. It's used in code
that only runs for dispatch_width == 8, so it doesn't matter,

Edited-by: Carl Worth <cworth@cworth.org>:
There is an internal implementation detail that the hash table
underlying the struct string_to_uint_map stores each value internally
as (value+1). The user needn't be very concerned with this (other than
knowing that a value of UINT_MAX cannot be stored) since put() adds 1
and get() subtracts 1.
So in this commit, rather than call the user's function directly with
hash_table_call_foreach, we call through a wrapper that fixes up the
off-by-one values before the caller's callback sees them.
And with this wrapper in place, we also give a better signature to the
callback function being passed to iterate(), so that this callback
function can actually expect a char* and an unsigned argument, (rather
than a couple of void* ).

format_utils: Use a more precise conversion when decreasing bits
When converting to a format that has fewer bits the previous code was just
shifting off the bits. This doesn't provide very accurate results. For example
when converting from 8 bits to 5 bits it is equivalent to doing this:
x * 32 / 256
This works as if it's taking a value from a range where 256 represents 1.0 and
scaling it down to a range where 32 represents 1.0. However this is not
correct because it is actually 255 and 31 that represent 1.0.
We can do better with a formula like this:
(x * 31 + 127) / 255
The +127 is to make it round correctly.
The new code has a special case to use uint64_t when the result of the
multiplication would overflow an unsigned int. This function is inline and
only ever called with constant values so hopefully the if statements will be
folded.
The main incentive to do this is to make the CPU conversion path pick the same
values as the hardware would if it did the conversion. This fixes failures

it's more efficient, but it's no longer needed. Also, if you do do your
own hashing, the hash set will assert that your hash matches what it
