anv: Stop setting BO flags in bo_init_new

The idea behind doing this was to make it easier to set various flags.
However, we have enough custom flag settings floating around the driver
that this is more of a nuisance than a help.  This commit has the
following functional changes:

 1) The workaround_bo created in anv_CreateDevice loses both flags.
    This shouldn't matter because it's very small and entirely internal
    to the driver.

 2) The bo created in anv_CreateDmaBufImageINTEL loses the
    EXEC_OBJECT_ASYNC flag.  In retrospect, it never should have gotten
    EXEC_OBJECT_ASYNC in the first place.

mesa: Remove GL_APPLE_vertex_array_object stubs

Mark the functions 'exec="skip"' in the XML instead.  libGL will still
have the functions, but the driver won't try to use them.  I verified
that this commit works with piglit's 'object-namespace-pollution glClear
vertex-array' on x64 with a driver built from mesa-12.0.3 tag.

In fairness, this test also works with a libGL built from 7927d03.  I
believe it continues to work because on non-Windows platforms we
generate some extra, dummy dispatch functions that can be used when a
driver requests a function unknown to libGL.  This was done to provide
some "forward" compatibility with drivers that need more functions.
This doesn't work on Windows because the Windows calling convention is
for the callee to clean up the stack.  That's the theory anyway.

util: Change the pointer hashing function

Use our knowledge that pointers are at least 4 byte aligned to remove
the useless digits. Then shift by 6, 10, and 14 bits and add this to
the original pointer, effectively folding in the entropy of the higher
bits of the pointer into a 4-bit section. Stopping at 14 means we can
add the entropy from 18 bits, or at least a 600Kbyte section of memory.
Assuming that ralloc allocates from a linearly allocated heap less than
this we can make a very efficient pointer hashing function for our usecase.
Even if we are not on an architecture that is 4 byte aligned, there is
still a high big chance that the thing we are allocating is at least
8 bytes in size, so even then we will have entropy into the third bit.

The 4 bit increment on the shifts is chosen rather arbitrarily; if we
had chosen a 3 bit increment we would need to add another xor to
cover a decently sized memorypool. Increasing it to 5 bits would
spread our entropy more, possibly hurting us with more collisions on
hash tables of size less than 32. With a hash table of size 16 there
are a max of 11 entries, and we can assume that with such a small table
collisions are not that painfull.

This allows us to hash the whole 32 or 64 bit pointer at once,
instead of running FNV1a, looping through each byte and doing
increments, decrements, muls, and xors on every byte. This cuts
_mesa_hash_data from 1.5 % on profiles, to making _mesa_hash_pointer
show up with a 0.09% share. Collisions on insertion actually seems to be
ever so slightly lower with this hash function, as found by printing
a loop counter and sorting the data.

perf stat shows a 1.5% reduction in instruction count,
and a 5% reduction in stalled cycles. Shader-db runtime goes
from 225 to 220 seconds.

No instruction-count changes in shader-db, but there are some minor
changes in cycle-count that is likely caused by nir walking a set
in some of its passes, and this causing a different ordering.
That might eventually lead to a difference in register allocation.
However, the effect is a net positive;

drirc: Add allow_glsl_builtin_variable_redeclaration for Dying Light and Dead Island Definitive Edition

This fixes the long-standing problem with Dying Light where the game would
produce a black screen when running under Mesa. This happened because the
game's vertex shaders redeclare gl_VertexID, which is a GLSL builtin.
Mesa's GLSL compiler is a little more strict than others, and would not
compile them:

    error: `gl_VertexID' redeclared

The allow_glsl_builtin_variable_redeclaration directive allows the shaders
to compile and the game to render. The game also requires OpenGL 4.4+ (GLSL
440), but does not request it explicitly. It must be forced with an
override, such as MESA_GL_VERSION_OVERRIDE=4.5 and
MESA_GLSL_VERSION_OVERRIDE=450. A compatibility context is *not* required
and forcing one with 4.5COMPAT or allow_higher_compat_version results in
graphical artifacts.

Dead Island Definitive Edition is another Techland port on the same engine
with the same problems, so we set the
allow_glsl_builtin_variable_redeclaration option for that game as well.

i965: Use the upload BO for push constants on Gen7.5-Gen8.

We can easily use the upload BO for push constants on Gen7.5/Gen8 too,
at the cost of a relocation when emitting 3DSTATE_CONSTANT_XS.  We can
simply switch to using constant buffer pointer 2 instead of pointer 0,
like we do on Gen9+.

Ivybridge and Baytrail can't do this trick because they require the
constant buffers to be enabled in order, starting with 0.  We'd have
to set the INSTPM bit to make the constant buffer pointer not relative
to dynamic state base address, which would need kernel command parser
support.

i965: Use the upload BO for push constants on Gen9+.

Shaders can use quite a bit of uniform data.  Better to put it in the
upload buffers, like we do for client vertex data, rather than the
batch buffer state area, which is primarly used for indirect state.

This should free up batch space, allowing us to emit more commands in a
batch before flushing.  Because BRW_NEW_BATCH also causes a lot of state
to be re-emitted, it may also reduce CPU overhead a little bit.

We took this approach on Gen4-5, but switched to using the batch area
on Gen6+ because buffer 0 is relative to Dynamic State Base Address by
default, which is set to the start of the batch.

On Gen9+, we already use a relocation due to a workaround, so this is
trivial to change and has basically no downside.

Unfortunately we can't change compute shader push constants because
MEDIA_CURBE_LOAD always uses an offset from dynamic state base address.

When we fallback currently the gl_program objects are re-allocated.

egl/wayland: Ensure we get a back buffer

Commit 9ca6711faa03 changed the Wayland winsys to only block for the
frame callback inside SwapBuffers, rather than get_back_bo. get_back_bo
would perform a single non-blocking Wayland event dispatch, to try to
find any release events which we had pulled off the wire but not
actually processed. The blocking dispatch was moved to SwapBuffers.

This removed a guarantee that we would've processed all events inside
get_back_bo(), and introduced a failure whereby the server could've sent
a buffer release event, but we wouldn't have read it. In clients
unconstrained by SwapInterval (rendering ~as fast as possible), which
were being displayed directly without composition (buffer release delayed),
this could lead to get_back_bo() failing because there were no free
buffers available to it.

The drawing rightly failed, but this was papered over because of the
path in eglSwapBuffers() which attempts to guarantee a BO, in order to
support calling SwapBuffers twice in a row with no rendering actually
having been performed.

Since eglSwapBuffers will perform a blocking dispatch of Wayland
events, a buffer release would have arrived by that point, and we
could then choose a buffer to post to the server. The effect was that
frames were displayed out-of-order, since we grabbed a frame with random
past content to display to the compositor.

Ideally get_back_bo() failing should store a failure flag inside the
surface and cause the next SwapBuffers to fail, but for the meantime,
restore the correct behaviour such that get_back_bo() no longer fails.
