i965: Apply depthstencil alignment workaround when doing fast clears.
Fast depth clears have the same depth/stencil alignment requirements as other drawing operations. Therefore, we need to call brw_workaround_depthstencil_alignment() from both the clear and drawing paths. Without this fix, we get image corruption if the following conditions hold: (a) the first ever drawing operation to a depth miplevel (or the first drawing operation after having used the texture for sampling) is a clear, (b) the depth miplevel has a size that is eligible for fast depth clears, and (c) the depth miplevel has an offset within the miptree that isn't 8x8 aligned. Fixes piglit "depthstencil-render-miplevels" tests with size 273. NOTE: This is a candidate for stable branches Reviewed-by: Chad Versace <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
