Logic is lifted from bi_layout.c, adapted to work on instructions (not
clauses) and for Valhall's off-by-one semantic which is annoyingly
different than Bifrost. (But the same as Midgard -- Bifrost was
annoyingly different than Midgard!)

Indirect dispatch is implemented using an extra compute job patching
the compute job header to apply the final num_workgroup values. Add
helpers to simplify emission of the such jobs.

pan_blitter.c is meant to replace the pan_blit.c which currently
provides helpers to preload the tile buffer. Some changes
are worth mentioning:

- we use pre-frame DCDs on Bifrost (Midgard still uses a tiler job
  to preload the tile buffer)
- the blit shaders are now stored in a hash table and created lazily
- we now cache blend shader binaries and blit RSDs too

This library will soon be extended to cover regular blits.

Previously, there was minimal support for interoperating with legacy
kernels (reusing kernel modules originally designed for proprietary
legacy userspaces, rather than for upstream-friendly free software
stacks). Now that the Panfrost kernel is stabilising, this commit drops
the legacy code path.

Panfrost users need to use a modern, mainline kernel supporting the
Panfrost kernel driver from this commit forward.

This patch adds an initial stub for the Gallium driver, containing
simple screen functions and the majority of the driver headers but no
actual functionality. It further adds the winsys glue for linking in
this stub driver via kmsro on Rockchip/Amlogic boards.

Instead in the common code, construct these shaders from TGSI.  For now
we let a2xx keep it's hand coded shaders, as it's compiler isn't quite
up to the job yet.  All the same it is a net drop in code size and gets
rid of special cases.

Currently works on a220.  Others in the a2xx family look pretty similar
and should be pretty straightforward to support with the same driver.

The a3xx has a new shader ISA, and while many registers appear similar,
the register addresses have been completely shuffled around.  I am not
sure yet whether it is best to support with the same driver, but
different compiler, or whether it should be split into a different
driver.

Mesa's chaining hash table for object names is slow, and this should be much
faster.  I namespaced the functions under _mesa_*, to avoid visibility
troubles that we may have had before with hash_table_* functions.

v2: Move .c file to main/, const a few things, clean up loop conditions,
    add/extend some comments.

This patch adjusts the aliasing pattern in the GL API description XML,
and the functions that implement the GL API within Mesa, to
consistently follow these naming conventions:

- When several function names are aliases of each other, the primary
  name is the one with no extension suffix (or the name with the
  suffix "ARB", if no unsuffixed name is available).  (By "primary
  name", I mean the name that all the other functions point to using
  the XML "alias" attribute).

- The name of the mesa implementation of each function is the same as
  the primary name, with the prefix "_mesa_".

This patch renames the following mesa functions:
  _check_GetTexGenxvOES => _mesa_GetTexGenxvOES
  _check_TexGenxOES => _mesa_TexGenxOES
  _check_TexGenxvOES => _mesa_TexGenxvOES
  _es_AlphaFuncx => _mesa_AlphaFuncx
  _es_ClearColorx => _mesa_ClearColorx
  _es_ClearDepthx => _mesa_ClearDepthx
  _es_ClipPlanef => _mesa_ClipPlanef
  _es_ClipPlanex => _mesa_ClipPlanex
  _es_Color...

This patch creates a header querymatrix.h, to allow functions defined
in querymatrix.c to be used from other .c files.  It also switches
from the nonstandard GL_APIENTRY to GLAPIENTRY.

We still don't inline for control flow in the inlined function, and we
don't have any limits on what we will inline.

This touches a lot of files because everything derived from ir_visitor
has to be updated.  This is the primary disadvantage of the visitor pattern.

The following tests now pass:

    glslparsertest/shaders/if1.frag
    glslparsertest/shaders/if2.frag

The following tests that used to pass now fail.  It appears that most
of these fail because ast_nequal and ast_equal are not converted to HIR.

    shaders/glsl-unused-varying.frag
    shaders/glsl-fs-sqrt-branch.frag

Also turn generate_swizzle into a static "create" method of the new
class; we'll want to use it for the IR reader as well.

Also make a slight change to ir_variable.  The ir_dereference tracks
the number of nested dereferences.  If an ir_variable is visited and
the count is non-zero, just print the name of the variable.

The ir_visitor class is the abstract base class for all visitors.
ir_print_visitor contains the beginnings of a concrete visitor class
that will print out an IR sequence in a Lisp / Scheme-like syntax.

The ast_expression_bin subclass is used for all binary expressions
such as addition, subtraction, and comparisons.  Several other
subclasses are soon to follow.
