gallium: enable int64 on radeonsi, llvmpipe, softpipe
All of these have had support for the TGSI opcodes since before most of
the glsl compiler work landed.
Also update the docs accordingly, including the missing note about i965.

+<h1>Mesa 17.1.0 Release Notes / TBD</h1>
+
+<p>
+Mesa 17.1.0 is a new development release.
+People who are concerned with stability and reliability should stick
+with a previous release or wait for Mesa 17.1.1.
+</p>
+<p>
+Mesa 17.1.0 implements the OpenGL 4.5 API, but the version reported by
+glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
+glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 4.5. OpenGL
+4.5 is <strong>only</strong> available if requested at context creation
+because compatibility contexts are not supported.
+</p>
+
+
+<h2>SHA256 checksums</h2>
+<pre>
+TBD.
+</pre>
+
+
+<h2>New features</h2>
+
+<p>
+Note: some of the new features are only available with certain drivers.
