Widens the given bit mask by a multiplier, meaning that it will
replicate each bit by that amount.
For example: 0b101 widened by 2 will become: 0b110011
This is typically used in shader I/O to transform a 64-bit
writemask to a 32-bit writemask.
Moving this function here because it is used in multiple places.

When using the Vulkan API, command buffers can be recorded way before
perfetto is enabled. This can be problematic if you want already
recorded command buffers to produce traces.
This new environment variable makes perfetto enabled internally so
that command buffers are recorded with timestamps, even though no
perfetto recording happens.

When cloning a chunk of tracepoints, we cannot just copy the elements
of the traces[] array. We also need the payloads associated with
those.
This change introduces a new u_trace_payloaf_buf object that is
refcounted so that we can easily import traces[] elements and their
payloads from one utrace to another.

As preparation for changing the behavior of LLVMpipe on IBM Z, add a
flag to detect that platform. As it is always known at compile-time, we
do not add it to the struct for cpu flags to avoid inflating that
struct's size.

turnip was playing fast and loose with the name, using the R8_G8B8 format
name but actually setting the descriptors up to read G8_B8R8 like Vulkan
(sensibly) wants. This caused trouble when trying to make freedreno and
turnip share code. By having both orderings as format names, we can share
the descriptor code and also confuse readers less.

Some filesystems don't fill in d_type in dirent. Resulting in
DT_UNKNOWN. Pass this entry through to the next step and use stat on the
full filepath to determine if it is a file.
sshfs is known to not fill d_type.
This resolves an issue where driconf living on an sshfs path wasn't
working.

Some applications may request an indirect context but this feature is
disabled by default on Xorg and thus context creation will fail.
This commit adds a drirc setting to force the creation of direct glx
context, regardless of what the app is requesting.

In the menu of CS:GO R8_SRGB textures are uploaded and read back, and
since R8_SRGB can't be read back on GLES, because it is not a rendertarget
format and glGetTexImage and siblings don't exists, we can't default to
enabling reading back this format. This leads to an emulation of the
glGetTexImage calls issued by CS:GO, and this slows down the menus a lot
(below 1 fps on Intel XE hosts).
So add this driconf tweak and enable it for CS:GO to work around the issue.
It can be done safely, because in this case we actually can use the data
that is stored on the host in the backing IOV.
This tweak lets the CS:GO menu run at around 60 FPS when run with virgl
on a Intel XE host when it would run with less than 1 FPS without the tweak.

The GLSL spec says it's an error if a shader statically writes to these
2 variables.
Until this commit, Mesa refused to link a shader if it had an unused
function writing to one of these variables while another (used) function
wrote to the other.
This commit adds an option to perform dead function elimination after
the intra-stage linking step but before performing these checks.
