llvmpipe: use global llvm context for PIPE_SUBSYSTEM_EMBEDDED
There's 2 reasons why we'd want to use the global context:
1) There still seems to be one memory "leak" left when using multiple llvm
contexts (it is not a true leak as the memory disappears into some still
addressable pool but nevertheless the memory consumption grows). See
http://cgit.freedesktop.org/~jrfonseca/llvm-jitstress/
2) These contexts get kinda big - even when disposing modules etc. after
compiling a shader the LLVMContext can easily be over 100kB. So when there's
lots of llvm contexts arounds it adds up.
The downside is that at least right now this is absolutely not thread safe,
so this only works safely in environments where multiple pipe contexts are not
used concurrently.

This is going to be useful because the Gen7+ uniform and varying pull

u_primconvert: add primitive restart support
This add primitive restart support to the prim conversion.
This involves changing the API for the translate functions
as we need to pass the prim restart index and the original
number of indices into the translate functions.
primitive restart is support for quads, quad strips
and polygons.
This deal with the case where the actual number of output
primitives is less than the initially calculated number,
by filling the rest of the output primitives with the restart
index, the other option is to reduce the output prim number,
but that will make the generator code a bit messier.

main: Add TEXTURE_CUBE_MAP support in CopyTextureSubImage3D.
So it turns out that this doesn't actually fix any bugs or add any features,
stictly speaking. However, it does avoid a lot of kludginess. Previously, if
you called
glCopyTextureSubImage3D(texcube, 0, 0, 0, zoffset = 3, ...
it would grab the texture image object for face = 0 in teximage.c instead of
the desired face = 3. But Line 274 of brw_blorp_blit.cpp would correct for
this by updating the slice to 3.
This commit does the correct thing before calling any drivers,

glsl: Annotate as_foo functions that the this pointer cannot be NULL
We use the idiom
ir_foo *x = y->as_foo();
if (x == NULL)

all over the place. GCC generates some quite lovely code for this.
One such example:
340a5b: 83 7d 18 04 cmpl $0x4,0x18(%rbp)
340a5f: 0f 85 06 04 00 00 jne 340e6b
340a65: 48 85 ed test %rbp,%rbp
340a68: 0f 84 fd 03 00 00 je 340e6b
This case used as_expression() (ir_type_expression is 4). Note that it
checks the ir_type, then checks that the pointer isn't NULL. There is
some disconnect in GCC around the condition in the as_foo functions.
return ir_type == ir_type_##TYPE ? (ir_##TYPE *) this : NULL; \
It believes "this" could be NULL, so it emits check outside the function
just for fun.
This patch uses assume() to tell GCC that it need not bother with extra
NULL checking of the pointer returned by the as_foo functions.

i965/fs: Emit better b2f of an expression on GEN4 and GEN5
On platforms that do not natively generate 0u and ~0u for Boolean
results, b2f expressions that look like
f = b2f(expr cmp 0)
will generate better code by pretending the expression is
f = ir_triop_sel(0.0, 1.0, expr cmp 0)
This is because the last instruction of "expr" can generate the
condition code for the "cmp 0". This avoids having to do the "-(b & 1)"
trick to generate 0u or ~0u for the Boolean result. This means code like
mov(16) g16<1>F 1F
mul.ge.f0(16) null g6<8,8,1>F g14<8,8,1>F
(+f0) sel(16) m6<1>F g16<8,8,1>F 0F

that the true (or false) case already results in zero would allow better
code generation by possibly avoiding a load-immediate instruction.

mesa: Replace _mesa_round_to_even() with _mesa_roundeven().
Eric's initial patch adding constant expression evaluation for
ir_unop_round_even used nearbyint. The open-coded _mesa_round_to_even
implementation came about without much explanation after a reviewer
asked whether nearbyint depended on the application not modifying the
rounding mode. Of course (as Eric commented) we rely on the application
not changing the rounding mode from its default (round-to-nearest) in
many other places, including the IROUND function used by
_mesa_round_to_even!
Worse, IROUND() is implemented using the trunc(x + 0.5) trick which
fails for x = nextafterf(0.5, 0.0).
Still worse, _mesa_round_to_even unexpectedly returns an int. I suspect
that could cause problems when rounding large integral values not
representable as an int in ir_constant_expression.cpp's
ir_unop_round_even evaluation. Its use of _mesa_round_to_even is clearly
broken for doubles (as noted during review).
The constant expression evaluation code for the packing built-in
functions also mistakenly assumed that _mesa_round_to_even returned a
float, as can be seen by the cast through a signed integer type to an
unsigned (since negative float -> unsigned conversions are undefined).
rint() and nearbyint() implement the round-half-to-even behavior we want
when the rounding mode is set to the default round-to-nearest. The only
difference between them is that nearbyint() raises the inexact
exception.
This patch implements _mesa_roundeven{f,}, a function similar to the
roundeven function added by a yet unimplemented technical specification
(ISO/IEC TS 18661-1:2014), with a small difference in behavior -- we
don't bother raising the inexact exception, which I don't think we care
about anyway.
At least recent Intel CPUs can quickly change a subset of the bits in
the x87 floating-point control register, but the exception mask bits are
not included. rint() does not need to change these bits, but nearbyint()
does (twice: save old, set new, and restore old) in order to raise the
inexact exception, which would incur some penalty.
