If an application requests a generic compressed format for a texture
and the driver does not pick a specific compressed format, return the
generic base format (e.g., GL_RGBA) for the GL_TEXTURE_INTERNAL_FORMAT
query.

We were primarily failing to convert in the NativeIntegers case, which
this fixes. However, we were also just truncating float uniforms when
converting to integer, which does not appear to be the correct
behavior. Note, however, that the NVIDIA drivers also truncate
instead of rounding.
GL_DOUBLE return type is dropped because it was never used and
completely broken. It can be added when there's test code.
Fixes piglit ARB_shader_objects/getuniform
v2: This is a rewrite of my previous glGetUniform patch, which Ken
pointed out missed storage_type-based conversions to integer,
which was totally broken still thanks to a typo in the testcase.
v3: Quote the spec justifying the rounding behavior.

It can now override both buffer offsets and strides in additions to resources.
Overriding buffer offsets was kinda hackish and could cause issues with
non-native vertex formats.
Without this we'd miss the last update in a sequence like {COLOR0, COLOR1},
{COLOR0}, {COLOR0, COLOR1}. I originally had a patch for this that called
updated_drawbuffers() when the buffer count changed, but later realized that
was wrong. The ARB_draw_buffers spec explicitly says "The draw buffer for
output colors beyond <n> is set to NONE.", and this is queryable state.
This fixes piglit arb_draw_buffers-state_change.

The flush extensions flush call indicates end of frame and should only

path, we call flush and then call dri2CopySubBuffer, which also calls

The purpose of the (irb->draw_offset & 4095) != 0 check was to ensure
that we don't have XYy offsets into a tile, since Gen4 hardware doesn't
support that. However, it's insufficient: there are cases where
draw_offset & 4095 is 0 but we still have a Y-offset. This leads to an
assertion failure in brw_update_renderbuffer_surface with tile_y != 0.
Instead, simply call intel_renderbuffer_tile_offsets to compute the
actual X/Y offsets and check if either are non-zero. This makes both
the workaround and the assertion check the same things.

The index buffer state emit only occurred if there was an IB in place
and we were in either a new batch or a new IB state. But because we
only flagged new IB state if IB state changed from the last IB state
we calculated, we could simply never emit IB state after batchbuffer
wraps if the first draw didn't use the IB and we didn't actually
change the IB.

(cherry picked from commit 818db3848b)
It turns out that internally the texture cache gets flushed in a
couple of cases, particularly around 2D operations mixed with 3D. In
almost all cases one of those happens between rendering to an
FBO-attached texture and rendering from that texture. However, as of
the next patch, glean tfbo (and the new fbo-flushing-2 test) would
manage to get stale texture values because one of those flushes didn't
occur. The intention of this code was always to get the render cache
cleared and ready to be used from the sampler cache (and it does on <=
gen4), so this just catches gen5 up.
This patch was also tested to fix fbo-flushing on gen7.

When emitting a MAC instruction in a vertex shader, brw_vs_emit()
calls accumulator_contains() to determine whether the accumulator
already contains the appropriate addend; if it does, then we can avoid
emitting an unnecessary MOV instruction.
However, accumulator_contains() wasn't checking the val.negate or
val.abs flags. As a result, if the desired value was the negation, or
the absolute value, of what was already in the accumulator, we would
generate an incorrect shader.

Commit 53c89c67f3 ("i965: Avoid generating
MOVs for assignments of expressions.") added the line "this->result =
reg_undef" all over the code. Unfortunately, since Eric developed his
patch before I landed Ivybridge support, he missed adding it to
fs_visitor::emit_texture_gen7() after rebasing.
Furthermore, since I developed TXD support before Eric's patch, I
neglected to add it to the gradient handling when I rebased.
Neglecting to set this causes the visitor to use this->result as storage
rather than generating a new temporary. These missing statements
resulted in the same register being used to store several different
values.

Previously the code would just look at deref->array->type to see if it
was a constant. This isn't good enough because deref->array might be
another ir_dereference_array... of a constant. As a result,
deref->array->type wouldn't be a constant, but
deref->variable_referenced() would return NULL. The unchecked NULL
pointer would shortly lead to a segfault.
Instead just look at the return of deref->variable_referenced(). If
it's NULL, assume that either a constant or some other form of
anonymous temporary storage is being dereferenced.
This is a bit hinkey because most drivers treat constant arrays as
uniforms, but the lowering pass treats them as temporaries. This
keeps the behavior of the old code, so this change isn't making things
worse.
