[Mesa-stable] [PATCH 1/3] i965: Call brw_cache_flush_for_render in predraw_resolve_framebuffer

[Jason Ekstrand]

This makes sure we flush things out such as depth writes prior to using
a surface through the render cache.  Besides the overhead of a hash
table look-up, this function is harmless to call repeatedly with the
same arguments.
