st/mesa: store mapping from perfmon counter to query type

Previously, when a performance monitor was initialized, an inner loop through
all driver queries with string comparisons for each enabled performance
monitor counter was used. This hurts when a driver exposes lots of queries.

gallium: remove pipe_driver_query_group_info field type

This was only used to implement an unnecessarily restrictive interpretation
of the spec of AMD_performance_monitor. The spec says

  A performance monitor consists of a number of hardware and software
  counters that can be sampled by the GPU and reported back to the
  application.

I guess one could take this as a requirement that counters _must_ be sampled
by the GPU, but then why are they called _software_ counters? Besides,
there's not much reason _not_ to expose all counters that are available,
and this simplifies the code.

gallivm: use sampler index 0 for texel fetches

texel fetches don't use any samplers. Previously we just set the same
number for both texture and sampler unit (as per "ordinary" gl style
sampling where the numbers are always the same) however this would trigger
some assertions checking that the sampler index isn't over PIPE_MAX_SAMPLERS
limit elsewhere with d3d10, so just set to 0.
(Fixing the assertion instead isn't really an option, the sampler isn't
really used but might still pass an out-of-bound pointer around and even
copy some things from it.)

I didn't like that commit to begin with -- computing things at compile

Anyway, by making brw_imm_vf4() take the actual 8-bit restricted floats
directly (instead of only integral values that would be converted to
restricted float), we can use this function as a replacement for the

i965: Allow indirect GS input indexing in the scalar backend.

This allows arbitrary non-constant indices on GS input arrays,
both for the vertex index, and any array offsets beyond that.

All indirects are handled via the pull model.  We could potentially
handle indirect addressing of pushed data as well, but it would add
additional code complexity, and we usually have to pull inputs anyway
due to the sheer volume of input data.  Plus, marking pushed inputs
as live due to indirect addressing could exacerbate register pressure
problems pretty badly.  We'd need to be careful.

i965/nir: Validate that NIR passes call nir_metadata_preserve().

Failing to call nir_metadata_preserve() can have nasty consequences:
some pass breaks dominance information, but leaves it marked as valid,
causing some subsequent pass to go haywire and probably crash.

This pass adds a simple validation mechanism to ensure passes handle
this properly.  We add a new bogus metadata flag that isn't used for
anything in particular, set it before each pass, and ensure it *isn't*
still set after the pass.  nir_metadata_preserve will reset the flag,
so correct passes will work, and bad passes will assert fail.

(I would have made these functions static inline, but nir.h is included
in C++, so we can't bit-or enums without lots of casting...)

i965/nir: Add OPT() and OPT_V() macros for invoking NIR passes.

OPT() is the normal macro for passes that return booleans, while OPT_V()
is a variant that works for passes that don't properly report progress.
(Such passes should be fixed to return a boolean, eventually.)

These macros take care of calling nir_validate_shader() and setting
progress appropriately.  In the future, it would be easy to add shader
dumping similar to INTEL_DEBUG=optimizer by extending the macro.
