When faced with code such as:

    mov vgrf31.0:UD, 960D
    mov vgrf31.1:UD, vgrf30.xxxx:UD

The dead code eliminator didn't consider reg_offsets, so it decided that
the second instruction was writing was writing to the same register as
the first one, and eliminated the first one.  But they're actually
different registers.

This fixes INTEL_DEBUG=shader_time for vertex shaders.  In the above
code, vgrf31.0 represents the offset into the shader_time buffer where
the data should be written, and vgrf31.1 represents the actual time
data.  With a completely undefined offset, results were...unexpected.

I think this is probably one of the few cases (maybe only case) where we
generate multiple MOVs to a large VGRF.  Normally, we just use them as

returns whether the type is an “integer (non-normalized)” format. I don't
think it makes sense to say whether a type is normalized or not because it
depends on what format it is used with. For example, GL_RGBA+GL_UNSIGNED_BYTE
is normalized but GL_RGBA_INTEGER+GL_UNSIGNED_BYTE isn't. If the normalized
comment is just a mistake then it still doesn't make much sense because it is
missing the packed-pixel types such as GL_UNSIGNED_INT_5_6_5. If those were
added then it effectively just returns type != GL_FLOAT.

That function was only used in _mesa_is_enum_format_or_type_integer. This
function effectively checks whether the format is non-normalized or the type
is an integer. I can't think of any situation where that check would make
sense.

As far as I can tell neither of these functions have ever been used anywhere

configure: correctly autodetect xvmc/vdpau/omx

Commit e62b7d38a1d (configure: autodetect video state-trackers
when non swrast driver is present) added a check that caused
the autodetection to be omitted when we have the swrast gallium
driver. Whereas it should have skipped the VL targets when only
swrast was selected.

i965: Set the fast clear color value for texture surfaces

When a multisampled texture is used for sampling the fast clear color value
needs to be programmed into the surface state. This was being left as all
zeroes so if the surface was cleared to a value other than black then it
wouldn't work properly. This doesn't matter for single-sample textures because
in that case the MCS buffer is resolved before it is used as a texture source.

i965: Fix Haswell discard regressions since Gen4-5 line AA fix.

In commit dc2d3a7f5c217a7cee92380fbf503924a9591bea, Iago accidentally
moved fire_fb_write() above the brw_pop_insn_state(), which caused the
SEND to lose its predication and change from WE_normal to WE_all.
Haswell uses predicated SENDs for discards, so this broke Piglit's
tests for discards.

We want the Gen4-5 MOV to be uncompressed, unpredicated, and unmasked,
but the actual FB write itself should respect those.  So, pop state
first, and force it again around the single MOV.
