i965: Use __attribute__((flatten)) on fast tiled teximage code.
The fast tiled texture upload code does not compile with GCC 4.8's -Og
optimization flag.
memcpy() has the always_inline attribute set. This poses a problem,
since {x,y}tile_copy_faster calls it indirectly via {x,y}tile_copy,
and {x,y}tile_copy normally aren't inlined at -Og.
Using __attribute__((flatten)) tells GCC to inline every function call
inside the function, which I believe was the author's intent.
Fix suggested by Alexander Monakov.
