Before resolving a rendertarget or a depth/stencil resource into a

It is unclear whether this is necessary for the following stall to
work properly, or whether the depth flush just adds enough time
for the color cache flush to finish before the resolver is started,
but this change removes artifacts that otherwise appear if a texture
is sampled directly after rendering into it.

The test case is a simple QML scene graph with a QtWebEngine based
WebView rendered on top of a blue background:

import QtQuick 2.0
import QtQuick.Window 2.2

WebView {

anchors.fill: parent
}

Component.onCompleted: {
webView.url = "<some animated website>"
}
}

If the website is animated, the WebView renders the site contents into
texture tiles and immediately afterwards samples from them to draw the
tiles into the Qt renderbuffer. Without this patch, a small irregular

if the texture sampler samples zeroes instead of the website contents,
and the previously rendered blue Rectangle shows through.

u_vector.h doesn't actually use anything from u_math, but it does mean
everyone has to pull in src/gallium/auxiliary/util includes.

anv/pipeline: use unsigned long long constant to check enable vertex inputs

When initializing the ANV pipeline, one of the tasks is checking which
vertex inputs are enabled. This is done by checking if the enabled bits
in inputs_read.

But the mask to use is computed doing `(1 << (VERT_ATTRIB_GENERIC0 +
desc->location))`. The problem here is that if location is 15 or
greater, the sum is 32 or greater. But C is handling 1 as a 32-bit
integer, which means the displaced bit is out of range and thus the full
value is 0.

Thus, use 1ull, which is an unsigned long long value.

This fixes:
dEQP-VK.pipeline.vertex_input.max_attributes.16_attributes.binding_one_to_one.interleaved

v2: use 1ull instead of BITFIELD64_BIT() (Matt Turner)

presumably because we trade pull loads for fills.
