it looks since ce1a137228 they are now included
in more places, in particular even for things buildable with msvc, and hence
those break the build.

Drop stdbool, due to the X server being a pain and having
struct members called bool, although I've sent a patch to fix
that we should retain stupidity here. Use unsigned char
which is what GLboolean is anyways.

Commit 17c7ead7 exposed a bug in how uniform loading happens in the
presence of discard. It manifested itself in an application as
randomly incorrect pixels on the borders of conditional areas.
This is due to how discards jump to the end of the shader incorrectly
for some channels. The current implementation checks each 2x2
subspan to preserve derivatives. When uniform loading via samplers
was turned on, it uses a full execution mask, as stated in
lower_uniform_pull_constant_loads(), and only populates four channels
of the destination (see generate_uniform_pull_constant_load_gen7()).
It happens incorrectly when the first subspan has been jumped over.
The series that implemented this optimization was done before the
changes to use samplers for uniform loads. Uniform sampler loads
use special execution masks and only populate four channels, so we
can't jump over those or corruption ensues.
This fix only jumps to the end of the shader if all relevant channels
are disabled, i.e. all 8 or 16, depending on dispatch. This
preserves the original GLbenchmark 2.7 speedup noted in commit
beafced2.
It changes the shader assembly accordingly:
before : (-f0.1.any4h) halt(8) 17 2 null { align1 WE_all 1Q };
after(8) : (-f0.1.any8h) halt(8) 17 2 null { align1 WE_all 1Q };
after(16): (-f0.1.any16h) halt(16) 17 2 null { align1 WE_all 1H };
v2: Cleaned up comments and conditional ordering.
v3: Fix typo.

UniformBufferSize is in bytes so we need to divide by 16 to get the
number of constant buffer slots. Also, the ureg_DECL_constant2D()
function takes first..last parameters so we need to subtract one
for the last value.

Before, we were always using the address register and indirect addressing
to index into a UBO constant buffer. With this change we only do that
when necessary.
Using the piglit bin/arb_uniform_buffer_object-rendering test as an
example:
Shader code:
uniform ub_rot {float rotation; };
...
m[1][1] = cos(rotation);
Before:
IMM[1] INT32 {0, 1, 0, 0}
1: UARL ADDR[0].x, IMM[1].xxxx
2: MOV TEMP[0].x, CONST[3][ADDR[0].x].xxxx
3: COS TEMP[1].x, TEMP[0].xxxx
After:
0: COS TEMP[0].x, CONST[3][0].xxxx

Otherwise, if we were creating a const buffer src register for a UBO
the index into the UBO was always zero.

To implement the unlit_centroid_workaround, previously we emitted
(+f0) pln(8) g20<1>F g16.4<0,1,0>F g4<8,8,1>F { align1 1Q };
(-f0) pln(8) g20<1>F g16.4<0,1,0>F g2<8,8,1>F { align1 1Q };
where the flag register contains the channel enable bits from g0.
Since the predicates are complementary, the pair of pln instructions
write to non-overlapping components of the destination, which is the
case that the dependency control hints are designed for.
Typically setting dependency control hints on predicated instructions
isn't safe (if an instruction doesn't execute due to the predicate, it
won't update the scoreboard, leaving it in a bad state) but since we
must have at least one channel executing (i.e., +f0 is true for some
channel) by virtue of the fact that the thread is running, we can put
the +f0 pln instruction last and set the hints:
(-f0) pln(8) g20<1>F g16.4<0,1,0>F g2<8,8,1>F { align1 NoDDClr 1Q };
(+f0) pln(8) g20<1>F g16.4<0,1,0>F g4<8,8,1>F { align1 NoDDChk 1Q };

This sequence (where both x and w are used afterwards) wasn't handled.
mul.sat x, y, z
...
mov.sat w, x
We assumed that if x was used after the mov.sat, that we couldn't
propagate the saturate modifier, but in fact x was already saturated.
So ignore the live range check if the producing instruction already
saturates its result. Cuts one instruction from hundreds of TF2 shaders.
