glsl: skip more uniform initialisation when doing fallback linking

Here we skip the recreation of uniform storage if we are relinking

have already been set by the application and we don't want to reset

Futhermore from the GL_APPLE_object_purgeable:

    "In contrast, by calling ObjectUnpurgeableAPPLE with an <option> of

    ObjectUnpurgeableAPPLE is called with the <option> set to
    UNDEFINED_APPLE, then ObjectUnpurgeableAPPLE will return the value

    "An INVALID_VALUE error is generated if texture is not the name of

Same wording applies to the compressed version.

_mesa_lookup_texture_err(). This patch uses _mesa_lookup_texture() instead

vkQueuePresentKHR() takes VkPresentInfoKHR pointer and includes a
pResults fields which must holds the results of all the images
requested to be presented. Currently we're not filling this field.

Also as a side effect we probably want to go through all the images
rather than stopping on the first error.

This commit also makes the QueuePresentKHR() implementation return the

glx/glvnd: Fix GLXdispatchIndex sorting

Commit 8bca8d89ef3b ("glx/glvnd: Fix dispatch function names and indices")
fixed the sorting of the array initializers in g_glxglvnddispatchfuncs.c
because FindGLXFunction's binary search needs these to be sorted
alphabetically.

That commit also mostly fixed the sorting of the DI_foo defines in
g_glxglvnddispatchindices.h, which is what actually matters as the
arrays are initialized using "[DI_foo] = glXfoo," but a small error
crept in which at least causes glXGetVisualFromFBConfigSGIX to not
resolve, breaking games such as "The Binding of Isaac: Rebirth" and
"Crypt of the NecroDancer" from Steam not working and possible causes
other problems too.

This commit fixes the last of the sorting errors, fixing these mentioned
games not working.

anv: Disable stencil writes when both write masks are zero

Vulkan doesn't have a stencilWriteEnable bit like it does for depth.
Instead, you have a stencil mask.  Since the stencil mask is handled as
dynamic state, we have to handle it later during command buffer
construction.  This, combined with a later commit, seems to help Dota2
on my Broadwell GT3e desktop by a couple percent because it allows the
hardware to move the depth and stencil writes to early in more cases.
