(cherry picked from commit 1569709663)
The derived state approach currently used (_RestartIndex) doesn't work:
in the GL_PRIMITIVE_RESTART_FIXED_INDEX case, the restart index depends
on the index buffer's data type, and that isn't known until draw time.
The existing code also fails to obey the GL 4.3 rules which say that
FIXED_INDEX takes precedence over normal primitive restart.
This helper function correctly determines the restart index, and will
replace the derived state.

(cherry picked from commit 959d076b30)
The derived _PrimitiveRestart enable flag combines the PrimitiveRestart
and PrimitiveRestartFixedIndex enable flags. However, DrawArrays is not
supposed to do FixedIndex restart:
From the OpenGL 4.3 Core specification, section 10.3.5 (page 302):
"If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not
performed for array elements transferred by any drawing command not
taking a type parameter, including all of the *Draw* commands other
than *DrawElements*."
The OpenGL ES 3.0 specification agrees by omission:
"When DrawElements, DrawElementsInstanced, or DrawRangeElements
transfers a set of generic attribute array elements to the GL..."
Notably, DrawArrays is not included in the list of draw calls that
take PRIMITIVE_RESTART_FIXED_INDEX into consideration.

All of the GLSL specs from GLSL 1.30 (and GLSL ES 3.00) onward contain
language requiring certain integer variables to be declared with the
"flat" keyword, but they differ in exactly *when* the rule is
enforced:
(a) GLSL 1.30 and 1.40 say that vertex shader outputs having integral
type must be declared as "flat". There is no restriction on fragment
shader inputs.
(b) GLSL 1.50 through 4.30 say that fragment shader inputs having
integral type must be declared as "flat". There is no restriction on
vertex shader outputs.
(c) GLSL ES 3.00 says that both vertex shader outputs and fragment
shader inputs having integral type must be declared as "flat".
Previously, Mesa's behaviour was consistent with (a). This patch
makes it consistent with (b) when compiling desktop shaders, and (c)
when compiling ES shaders.
Rationale for desktop shaders: once we add geometry shaders, (b) really
seems like the right choice, because it requires "flat" in just the
situations where it matters. Since we may want to extend geometry
shader support back before GLSL 1.50 (via ARB_geometry_shader4), it
seems sensible to apply this rule to all GLSL versions. Also, this
matches the behaviour of the nVidia proprietary driver for Linux, and
the expectations of Intel's oglconform test suite.
Rationale for ES shaders: since the behaviour specified in GLSL ES
3.00 matches neither pre-GLSL-1.50 nor post-GLSL-1.50 behaviour, it
seems likely that this was a deliberate choice on the part of the GLES
folks to be more restrictive. Also, the argument in favor of (b)
doesn't apply to GLES, since it doesn't support geometry shaders at
all.
Some discussion about this has already happened on the Mesa-dev list.

just copies the depth data, not the HiZ data. This is reasonable,
since the alignment restrictions of HiZ are a large part of the reason
why the miptree had to be broken apart in the first place. However,
in order for the depth copy to be sufficient, we need to do a depth
resolve first, to make sure any deferred depth writes that are in the
