agx: Don't overallocate registers

We need to account for the full vector lengths. Especially important once we
start restricting the reg file.

agx: Coalesce more collects

Try harder to coalesce collects, by trying to allocate collects only to regions
of the register file where we actually have a full vector worth of registers
free. If we already know that the vector will be blocked later, it's not a good
base register to pick since we'd be force to shuffle later. So, this tweak to
the collect coalescing heuristic lets us eliminate a pile of pointless copying.

shader-db results are excellent. Note that, although we use more registers,
none of the shaders tested had their thread count affected, likely because the
max HURT isn't too high and most of the scary % here is from using a few more
registers when the register pressure is already low. In the near future, that
property will become guaranteed thanks to live range splitting, too.

exactly when it can use more registers without hurting performance. In the
present, it's just used for better shader-db statistics.

nir/loop_analyze: Determine iteration counts for more kinds of loops

If loop iterator is incremented with something other than regular
addition, it would be more error prone to calculate the number of

nir/loop_analyze: Add a function to evaluate an ALU as constant

...with a substitution. This function is largely a copy-and-paste of
try_fold_alu (nir_opt_constant_folding.c), and an argument could be made
that this function belongs in that file.

glx: Fix error handling yet again in CreateContextAttribs

Unlike the legacy CreateContext path, we would try to send the
GLXCreateContextAttribs request regardless of whether we'd successfully
created the client context state. And there's not a lot on the server
side to go wrong besides BadAlloc, so if the request succeeded but
the client side didn't we'd need to destroy the server context and
synthesize an X error. Since that itself involves more X protocol it's
tricky to get the request number right in the error, and tests and apps
can notice when you get it wrong.

Since we have now fixed client-side validation to generate the right
errors at the right times, this patch does something simpler, we match
CreateContext and fail early if the client-side setup fails. Now there's
no question of what request number to use, because we haven't sent any
protocol, the error is for the request as if it'd been sent.

dri: Validate more of the context version in validate_context_version

There's two kinds of "bad version" you might encounter here, either the
combination does not name a defined version (like 1.7) or it names
something the driver can't do (like asking r300 to do 4.0). EGL does not
distinguish these cases, but GLX calls them BadMatch and GLXBadFBConfig
respectively.

Since api_mask is the set of driver supported APIs, and we can only
support defined APIs, don't check it early in driCreateContextAttribs,
just let it fall out from validate_context_version.

glx/dri: Use X/GLX error codes for our create_context_attribs

This has no functional change because everyone calling this is
discarding the error code, because we're relying on the server to
generate the right thing for us. But we create the direct context first
and the server isn't going to enforce everything we want it to
(supported GL versions for example). Convert out from DRI error codes to
X/GLX error codes so we can fail the right way on the client side. We're
still throwing the error away in all of the callers but that'll change
shortly.
