Because branch conditions have to be in the pass slot, there is no
unconditional branch, and realistically the pass slot has to contain a
move when branching (there's nothing it does that would be useful for
operating on booleans, so we can't use it for anything when computing
the branch condition), we put the branch instruction in the pass slot
and at codegen time turn it into a move of the branch condition. This
means that it doesn't have to be special-cased like store instructions
are in the scheduler. Because of this decision we can remove the
half-implemented BRANCH codegen slot. Finally, we (ab)use the existing
schedule_first mechanism to make sure that branches are always last in
the basic block.

When picking a node to be scheduled, we try to schedule its children as
well. But we shouldn't try to schedule nodes which only have a fake
dependency on the original node, since this isn't the point of
scheduling children at the same time and can break some expectations of
the rest of the code.

This is the GLX counterpart to EGL_KHR_no_config_context. Contexts may
now be created without reference to an fbconfig, in which case it is
treated as compatible with any fbconfig (and thus any GLX drawable).

Somewhat terrifyingly, we never sent this for direct contexts, which
means the server never knew the context/drawable bindings. To handle
this sanely, pull the request code up out of the indirect backend, and
rewrite the context switch path to call it as appropriate. This
attempts to preserve the existing behavior of not calling unbind() on
the context if its refcount would not drop to zero.
Of course, you can't just do this indiscriminately, because this is GLX
and extant X servers have bugs and everything is terrible. To wit:
- For 1.20.x prior to 1.20.6, you can bind a direct context once, but
the second time you try to modify the context's binding you will get
GLXBadContextTag. This includes unbinding the context. And "deleting"
the context will leak memory, because it will still appear to be
current.
- For 1.19 and earlier, glXMakeCurrent(dpy, None, ctx) should be legal
for GL 3.0+ contexts, but the server will throw BadMatch.
To guard against this, we only send the request for indirect contexts
unless the server is known good, and only mention one context at a time
in such a request; if switching between contexts, we first unbind the
old, and then bind the new. Note that the second VendorRelease() version
is to catch XFree86 4.x and Xorg [67].x, which almost certainly have the
above bugs. Other servers might report different version numbers here,
but we can't do direct rendering against them, so this should be safe.
Fixes glx-make-context, glx-multi-window-single-context and
glx-query-drawable-glx_fbconfig_id-window. Sufficiently old piglit will
regress on glx-make-glxdrawable-current (throwing BadMatch), which is
fixed by mesa/piglit!116.
From the MEDIA_VFE_STATE docs:
"Starting with this configuration, the Maximum Number of Threads must
be set to (#EU * 8) for GPGPU dispatches.
Although there are only 7 threads per EU in the configuration, the
FFTID is calculated as if there are 8 threads per EU, which in turn
requires a larger amount of Scratch Space to be allocated by the
driver."
It's pretty clear that we need to increase this for scratch address
calculations, because the FFTID has a certain bit-pattern. The quote
above seems to indicate that we should increase the actual thread count
programmed in MEDIA_VFE_STATE as well, but we think the intention is to
only bump the scratch space.

This reverts commit 729de1488f.
It turns out that, although the register is in the logical context,
it isn't whitelisted, so we can't actually write it from userspace
batch buffers. The write just becomes a noop, which is why we saw
no performance changes.
I manually whitelisted it, and still observed no performance gains, but
it did regress KHR-GL46.texture_cube_map_array.color_depth_attachments
on the iris driver. So we might need to fix something before enabling
this. To prevent it randomly getting turned on should the kernel ever
whitelist this register, we revert the patch for now.
'α' has never appeared in any genxml files, so there's no need to
replace it with the word "alpha".

In a3268599f3, I attempted to fix nir_repair_ssa for unreachable
blocks. However, that commit missed the possibility that the use is in
a block which, itself, is unreachable. In this case, we can end up in
an infinite loop trying to replace a def with itself. Even though a
no-op replacement is a fine operation, it keeps extending the end of the
uses list as we're walking it. Instead of explicitly checking for the
group of conditions, just check if the phi builder gives us a different
def. That's guaranteed to be 100% reliable and, while it lacks symmetry
with the is_valid checks, should be more reliable.

pipe->clear() is not called for partial clears, which mesa emulates by
drawing a quad.
Furthermore, drivers should not use rasterizer state information for
scissor information (which was being used to handle the partial clears).
So, remove the partial clear support since it was not supposed to be
handled by pipe->clear() anyway.
This fixes issues with clearing after switching to different sized
framebuffers.

Allocating BOs is expensive, so we should avoid doing that by caching
freed BOs.
BO cache is modelled after one in v3d driver and works as follows:
- in lima_bo_create() check if we have matching BO in cache and return
it if there's one, allocate new BO otherwise.
- in lima_bo_unreference() (renamed from lima_bo_free()): put BO in
cache instead of freeing it and remove all stale BOs from cache
