r600g/radeonsi: send endian info to format translation functions

Because r600 GPUs can't do swap in their DB unit, we need to disable
endianess swapping for textures that are handled by DB.

There are four format translation functions in r600g driver:

- r600_translate_texformat
- r600_colorformat_endian_swap
- r600_translate_colorformat
- r600_translate_colorswap

This patch adds a new parameters to those functions, called
"do_endian_swap". When running in a big-endian machine, the calling
functions will check whether the texture/color is handled by DB -
"rtex->is_depth && !rtex->is_flushing_texture" - and if so, they will
send FALSE through this parameter. Otherwise, they will send TRUE.

The translation functions, in specific cases, will look at this parameter
and configure the swapping accordingly.

v4:
evergreen_init_color_surface_rat() is only used by compute and don't
handle DB surfaces, so just sent hard-coded FALSE to translation
functions when called by it.

This is mostly for variables that are only used in asserts and cause
unused-but-set-variable warnings in release builds. Could just use
UNUSED directly, but MAYBE_UNUSED should be less confusing and is
similar to what the Linux kernel has.

And yes __attribute__((unused)) can be used on variables on both GCC 4.2

combineLd/St would combine, i.e. :

st  u32 # g[$r2+0x4] $r3

freedreno/a4xx: better workaround for astc+srgb

variants/revisions.  But setting the SRGB bit in sampler view state

i965: Introduce state flag for blorp

In the past, BLORP has clobbered all BRW_NEW_* state flags, to trigger
re-emission of the entire 3D pipeline on the next draw.  However, there
are some packets BLORP simply leaves alone, so there's no need to
re-emit them.  Trying to reduce the set of dirty bits flagged after
BLORP runs is tricky.

Instead, we introduce a BRW_NEW_BLORP flag.  This should be set on any
atom which emits a packet that BLORP also emits.  When BLORP runs, it
will flag BRW_NEW_BLORP, causing those packets to get re-emitted.

This also makes it easy to avoid re-emitting specific atoms - we can
simply drop the BRW_NEW_BLORP flag on those.

To start, we assume that all packets need to be re-emitted.  This is the
safest approach and closest to the existing code's behavior.  Many of
these are obviously not required, and can be dropped in subsequent
patches.
