Pre-Gen6, the SF thread requires exact matching between VS output
slots (aka VUE slots) and FS input slots, even when the corresponding
VS output slot is unused due to being overwritten by point coordinate
replacement (glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE)).
As a result, we have a special hack in the VS to ensure when any
texture coordinate is subject to point coordinate replacement, it is
always allocated space in the VUE, even if it isn't written to by the
VS.
This hack isn't needed from Gen6 onwards, since SF (Gen7: SBE)
swizzling has the ability to insert the point coordinate into
gl_TexCoord[] without needing a corresponding unused VUE slot.
Note that no modification of SF setup code is required for this
patch--get_attr_override() already does the right thing. However, we
make a slight comment change to clarify why this works.
In addition to eliminating unnecessary VS recompiles and saving
precious URB space on Gen6+, this will save us the trouble of having
to adjust this hack when we implement geometry shaders.

GLX_INTEL_swap_event is broken on the server side, where it's
currently unconditionally enabled. This completely breaks
systems running on drivers which don't support that extension.
There's no way to test for its presence on this side, so instead
of disabling it uncondtionally, just disable it for drivers
which are known to not support it. It makes sense because
most drivers do support it right now.
We'll be able to remove this once Xserver properly advertises
GLX_INTEL_swap_event.

It has become a bit messy.
Changes:
- finally correct checking for transfer ops depending on the base format
- making sure the base internal format and the texture format match
(we were ignoring it, but it's important for correctness)
- the way-too-strict rule that both src and dst base formats must be the same
was dropped; ensuring the simpler and more permissive rule mentioned above
is enough
- stop using util_blit_pixels; pipe->blit is flexible enough, and now that we
have RGBX and red-alpha formats, pipe->blit can be used for more cases
Reviewed-by: Brian Paul <brianp@vmware.com>
A temporary texture is created such that it matches the format and type
combination and pixels are copied to it using memcpy. Then the blit is used to
copy the temporary texture to the texture image being modified by TexImage or
TexSubImage. The blit takes care of the format and type conversion and
swizzling. The result is a very fast texture upload involving as little CPU
as possible.
This improves performance in apps which upload textures during rendering.
An example is the Wine OpenGL backend for DirectDraw, which I used to test
the game StarCraft. Profiling had shown that TexSubImage was taking 50% of
CPU time without this patch, which was the main motivation for this work, and
now TexSubImage only takes 14% of CPU time. I had to underclock my CPU to see
any difference in the game and this patch does make the game a lot faster
if the CPU is slow (or using the powersave cpufreq profile).

The emulation of these if there's no rounding instruction available
is a bit more complicated than what the code did.
In particular, doing fp-to-int/int-to-fp will not work if the exponent
is large enough (and with NaNs, Infs). Hence such values need to be filtered
out and the original value returned in this case (which fortunately should
always be exact). This comes at the expense of performance (if your cpu
doesn't support rounding instructions).
Furthermore, floor/ifloor/ceil/iceil were affected by precision issues for
values near negative (for floor) or positive (for ceil) zero, fix that as well
(fixing this issue might not actually be slower except for ceil/iceil if the
type is not signed which is probably rare - note iceil has no callers left
in any case).
Also add some new rounding test values in lp_test_arit to actually test
for that stuff (which previously would have failed without sse41).
