i965: Add a RGBX->RGBA fallback for glEGLImageTextureTarget2D()

This enables support for importing RGBX8888 EGLImage textures on
Skylake.

Chrome OS needs support for RGBX8888 EGLImage textures because because
the Android framework produces HAL_PIXEL_FORMAT_RGBX8888 winsys
surfaces, which the Chrome OS compositor consumes as dma_bufs.  On
hardware for which RGBX is unsupported or disabled, normally core Mesa
provides the RGBX->RGBA fallback during glTexStorage.  But the DRIimage
code bypasses core Mesa, so we must do the fallback in i965.

mesa: Add _mesa_format_fallback_rgbx_to_rgba() [v2]

The new function takes a mesa_format and, if the format is an alpha
format with a non-alpha variant, returns the non-alpha format.
Otherwise, it returns the original format.

Example:
  input -> output

  // Fallback exists
  MESA_FORMAT_R8G8B8X8_UNORM -> MESA_FORMAT_R8G8B8A8_UNORM
  MESA_FORMAT_RGBX_UNORM16 -> MESA_FORMAT_RGBA_UNORM16

  // No fallback
  MESA_FORMAT_R8G8B8A8_UNORM -> MESA_FORMAT_R8G8B8A8_UNORM
  MESA_FORMAT_Z_FLOAT32 -> MESA_FORMAT_Z_FLOAT32

i965 will use this for EGLImages and DRIimages.

v2 (Jason Ekstrand):

nv50/ir: fix combineLd/St to update existing records as necessary

Previously the logic would decide that the record is kept, which
translates into keep = false in the caller, which meant that these
passes did not run.

While it's right that keep = false which means that a new record does
not need to be added, we do still have to perform the usual list
maintenance. It's easiest to do this pre-merge rather than post.

The lowering that clip/cull distance passes produce triggers this bug in
TCS (since reading outputs is done differently in other stages), but it
should be possible to achieve it with the right sequence of regular
reads/writes.

nv50/ir: adjust overlapping logic to take fileIndex-relative offsets

If the fileIndex is different, that means they are in logically
different spaces. However if there's also a relative offset, then they
could end up pointing at the same spot again.

Also add a note about potential for multiple buffers to overlap even if
they're at different file indexes. However that's potentially lowered
away by the point that this logic hits.
