Incremental builds were failing because not all generated source files
were missing dependencies to src/mapi/glapi/gen/*.xml.
Hopefully this change will be the end of these incremental build
failures.
This avoids a defect in lower_output_reads.
The problem is lower_output_reads treats the gl_FragData array as a single
variable. It first redirects all output writes to a temporary variable (array)
and then writes the whole temporary variable to the output, generating
assignments to all elements of gl_FragData.
BTW this pass can be modified to lower all arrays, not just inputs and outputs.
The question is whether it is worth it.

Fix the linker to deal with intrinsic functions which are undefined
all the way down to the driver back-end, and introduce intrinsic
definition helpers in the built-in generator.
We still need to figure out what kind of interface we want for drivers
to communicate to the GLSL front-end which of the supported intrinsics
should use a default GLSL implementation and which should use a
hardware-specific override. As there's no default GLSL implementation
for atomic ops, this seems like something we can worry about later on.

These ralloc contexts belong to a specific object and are being
deallocated manually from the class destructor. Now that we've hooked
up destructors to ralloc there's no reason for them to be children of
any other context, and doing so might to lead to double frees under
some circumstances. The class destructor has all the responsibility
of freeing class memory resources now.
This patch makes sure that class destructors are called as they should
be when a C++ object allocated by ralloc is released.
Based on a previous patch by Kenneth Graunke, but it doesn't exhibit
the ~0.8% performance regression in shader compilation times because
we now use the HAS_TRIVIAL_DESTRUCTOR() macro to detect the typical
case where the indirect function call can be avoided because the
object's destructor doesn't need to do anything.

The layer coming from GS needs to be clamped (not sure if that's actually
the correct error behavior but we need something) as the number can be higher
than the amount of layers in the fb. However, this code was using the layer
calculation from the scene, and this was actually calculated in
lp_scene_begin_rasterization() hence too late (so setup was using the value
from the _previous_ scene or just zero if it was the first scene).
Since the value is used in both rasterization and setup, move calculation up
to lp_scene_begin_binning() though it's a bit more inconvenient to calculate
there. (Theoretically could move _all_ code which was in
lp_scene_begin_rasterization() to there, because ever since we got rid of
swizzled render/depth buffers our "map" functions preparing the fb data for
render don't actually change the data in there at all, but it feels like
it would be a hack.)

Orbital Explorer was generating a 4000 instruction geometry shader, which
was taking 275 trips through dead code elimination and register
coalescing, each of which updated live variables to get its work done, and
invalidated those live variables afterwards.
By using bitfields instead of bools (reducing the working set size by a
factor of 8) in live variables analysis, it drops from 88% of the profile
to 57%, and reduces overall runtime from I-got-bored-and-killed-it (Paul
says 3+ minutes) to 10.5 seconds.

There is nothing in the OpenGL specification which prevents the user from
calling glGenQueries to generate a new query object while another object is
active. Neither is there anything in the Mesa implementation which prevents
this. So remove the INVALID_OPERATION errors in this case.
Similarly, it is explicitly allowed by the OpenGL specification to delete an
active query, so remove the assertion for that case, replacing it with the
necesssary state updates to end the query, (clear the bindpt pointer and call
into the driver's EndQuery hook).
