Now that we can use the much simpler rgba8_copy function, we don't need to
hand different functions out based on direction.

The SSSE3 swizzling code was written for fast uploads to the GPU and
assumed the destination was always 16-byte aligned. When we began using
this code for fast downloads as well we didn't do anything to account
for the fact that the destination pointer given by glReadPixels() or
glGetTexImage() is not guaranteed to be suitably aligned.
With SSSE3 enabled (at compile-time), some applications would crash when
an SSE aligned-store instruction tried to store to an unaligned
destination (or an assertion that the destination is aligned would
trigger).
To remedy this, tell intel_get_memcpy() whether we're uploading or
downloading so that it can select whether to assume the destination or
source is aligned, respectively.

This commit addes tiled copy functions for coping from tiled memory to
linear memory. These are very similar to the existing linear-to-tiled
paths.

This commit refactors the tiled_memcpy code in intel_tex_subimage.c and
moves it into its own file intel_tiled_memcpy files. Also, xtile_copy and
ytile_copy are renamed to linear_to_xtiled and linear_to_ytiled
respectively. The *_faster functions are similarly renamed.
There was also a bit of logic to select between the the libc provided
memcpy function and our custom memcpy that does an RGBA -> BGRA swizzle.
This was moved into an intel_get_memcpy function so that rgba8_copy can
live (and be inlined) in intel_tiled_memcpy.c.
v2: Jason Ekstrand <jason.ekstrand@intel.com>
- Better commit message
- Fix up the copyright on the intel_tiled_memcpy files
- Various whitespace fixes
- Moved a bunch of stuff that did not need to be exposed from
intel_tiled_memcpy.h to intel_tiled_memcpy.c
- Added proper documentation for intel_get_memcpy
- Incorperated the ptrdiff_t tweaks from commit 225a09790
v3: Jason Ekstrand <jason.ekstrand@intel.com>
- Fixed a comment
- Move the tile size constants into the .c file
