git_sha1_gen: accept MESA_GIT_SHA1_OVERRIDE env var
If one uses a parent build script to download/build Mesa we may not
have a full git repository (maybe a tar archive) so the 'git rev-parse'
command will fail.
This updates the script to look for a MESA_GIT_SHA1_OVERRIDE env var.
If it's set, use that sha1 instead of using git rev-parse. With this
change we can put a git hash in the GL_VERSION string even when we
don't have a git repo.

mesa: Expose GL_OES_required_internalformat on GLES contexts.
This extension is effectively a backport of GLES3's internalformat
handling to GLES 1/2. It guarantees that sized internalformats specified
for textures and renderbuffers have at least the specified size stored.
That's a pretty minimal requirement, so I think it can be dummy_true and
exposed as a standard in Mesa.
As a side effect, it also allows GL_RGB565 to be specified as a texture
format, not just as a renderbuffer. Mesa had previously been allowing 565
textures, which angered DEQP in the absence of this extension being
exposed.
v2: Allow 2101010rev with sized internalformats even on GLES3, citing the

i965/tes: account for the fact that dvec3/4 inputs take two slots
When computing the total size of the URB for tessellation evaluation
inputs we were not accounting for this, and instead we were always
assuming that each input would take a single vec4 slot, which could
lead to computing a smaller read size than required. Specifically, this
is a problem when the last input is a dvec3/4 such that its XY components
are stored in the the second half of a payload register (which can happen
if the offset for the input in the URB is not 64-bit aligned because
there are 32-bit inputs mixed in) and the ZW components in the
first half of the next, as in this case we would fail to account for the
extra slot required for the ZW components.

c7affbf687 enabled GLSLOptimizeConservatively on some
drivers. The idea was to speed up compile times by running
the GLSL IR passes only once each time do_common_optimization()
is called. However loop unrolling can create a big mess and
with large loops can actually case compile times to increase
significantly due to a bunch of redundant if statements being
propagated to other IRs.
Here we make sure to clean things up before moving on.
There was no measureable difference in shader-db compile times,
but it makes compile times of some piglit tests go from a couple
of seconds to basically instant.

glsl: make loop unrolling more like the nir unrolling path
The old code assumed that loop terminators will always be at
the start of the loop, resulting in otherwise unrollable
loops not being unrolled at all. For example the current
code would unroll:
int j = 0;
do {
if (j > 5)
break;
... do stuff ...
j++;
} while (j < 4);
But would fail to unroll the following as no iteration limit was
calculated because it failed to find the terminator:
int j = 0;
do {
... do stuff ...
j++;
} while (j < 4);
Also we would fail to unroll the following as we ended up
calculating the iteration limit as 6 rather than 4. The unroll
code then assumed we had 3 terminators rather the 2 as it
wasn't able to determine that "if (j > 5)" was redundant.
int j = 0;
do {
if (j > 5)
break;
... do stuff ...
if (bool(i))
break;
j++;
} while (j < 4);
This patch changes this pass to be more like the NIR unrolling pass.
With this change we handle loop terminators correctly and also
handle cases where the terminators have instructions in their
branches other than a break.
V2:
- fixed regression where loops with a break in else were never
unrolled in v1.
- fixed confusing/wrong naming of bools in complex unrolling.
