The fragment shader compiler has a number of checks like:

This patch introduces a new no16() function which replaces the above

Even better, we now have a single array describing the layout of

to be sequential starting from zero, and the resulting register number
would be used directly as an index into the params[] array.

This renumbering made it difficult to collect and save information about
pull constant locations, since setup_pull_constants() and
move_uniform_array_access_to_pull_constants() used different names.

This patch generalizes setup_pull_constants() to decide whether each
uniform register should be a pull constant, push constant, or neither
(because it's unused).  Then, it stores mappings from UNIFORM register
numbers to params[] or pull_params[] indices in the push_constant_loc
and pull_constant_loc arrays.  (We already did this for pull constants.)

Then, assign_curb_setup() just needs to consult the push_constant_loc
array to get the real index into the params[] array.

This effectively folds all the remove_dead_constants() functionality
into assign_constant_locations(), while being less irritable to work

2. Mechanically rewrite the instruction stream to pull the uniform

In order to support pull constants in SIMD16 mode, we will need to make

For the moment, a single invocation of demote_pull_constants can't

i965/fs: Save push constant location information.

Previously, both move_uniform_array_access_to_pull_constants() and
setup_pull_constants() maintained stack-local arrays with this
information.  Storing this information will allow it to be used from
multiple functions, allowing us to split and move code around.

We'll also eventually want to pass pull constant location information
to the SIMD16 compile.  Saving this information will help us do that.

Unfortunately, the two functions *cannot* share the contents of the
array just yet.  remove_dead_constants() renumbers all the UNIFORM
registers to be contiguous starting at zero, so the two functions
talk about uniforms using different names.  We can't even remap them,
since move_uniform_array_access_to_pull_constants() deletes UNIFORM
registers that are only accessed with reladdr, so remove_dead_constants
can't even see them.

This situation will improve in the next few patches.

egl/main: Stop using EGLNative types internally

Internally, much of the EGL code uses EGLNativeDisplayType,
EGLNativeWindowType, and EGLPixmapType. However, the EGLNative type
often does not match the variable's actual type.

The concept of EGLNative types are a bad match for Linux, as explained
below. And the EGL platform extensions don't use EGLNative types at all.
Those extensions attempt to solve cross-platform issues by moving the
EGL API away from the EGLNative types.

The core of the problem is that eglplatform.h can define each EGLNative
type once only, but Linux supports multiple EGL platforms.

To work around the problem, Mesa's eglplatform.h contains multiple
definitions of each EGLNative type, selected by feature macros. Mesa
expects EGL clients to set the feature macro approrpiately. But the
feature macros don't work when a single codebase must be built with
support for multiple EGL platforms, *such as Mesa itself*.

When building libEGL, autotools chooses the EGLNative typedefs based on
the first element of '--with-egl-platforms'. For example,
'--with-egl-platforms=x11,drm,wayland' defines the following:

    typedef Display* EGLNativeDisplayType;
    typedef Window   EGLNativeWindowType;
    typedef Pixmap   EGLNativePixmapType;

Clearly, this doesn't work well for Wayland and GBM.  Mesa works around
the problem by casting the EGLNative types to different things in
different files.

For sanity's sake, and to prepare for the EGL platform extensions, this
patch removes from egl/main and egl/dri2 all internal use of the
EGLNative types. It replaces them with 'void*' and checks each explicit
cast with a static assertion. Also, the patch touches egl_gallium the
minimal amount to keep it compatible with eglapi.h.

egl/dri2: Consolidate eglTerminate

egl_dri2.c:dri2_terminate() handled terminating X11 and DRM displays.
The Wayland platform implemented its own dri2_wl_terminate(), which was
nearly a copy of the common one.

To implement the EGL platform extensions, we either need to dispatch
eglTerminate per display or define a common implementation for all
platforms. This patch chooses consolidation.  It removes
dri2_wl_terminate() by folding it into the common dri2_terminate().

It was necessary to invert the `if (disp->PlatformDisplay == NULL)` and
the switch statement because, unlike DRM and X11, Wayland's terminator
performed action even when EGL didn't own the native display. In the
inversion, I replaced `disp->PlatformDisplay == NULL` with
`dri2_dpy->own_device` because the two expressions are synonymous, but
the latter's meaning is clearer.
