i965/eu: Change gen == 7 to gen >= 7 in a couple brw_eu_emit.c cases.

Broadwell is going to use the brw_eu_emit.c code soon.  We want to get
the fake MRF handling and URB HWord channel mask handling.

We don't need the CMP thread switch workaround, though.

i965/eu: Explicitly disable instruction compaction on Broadwell for now.

Until now, it's been off implicitly: we never call the compactor
function.  When we merge the generators, we'll start calling it, so we
should make it do nothing.

Matt will enable instruction compaction properly later.

i965/eu: Refactor jump distance scaling to use a helper function.

Different generations of hardware measure jump distances in different
units.  Previously, every function that needed to set a jump target open
coded this scaling, or made a hardcoded assumption (i.e. just used 2).

Most functions start with the number of instructions to jump, and scale
up to the hardware-specific value.  So, I made the function match that.

Others start with a byte offset, and divide by a constant (8) to obtain
the jump distance.  This is actually 16 / 2 (the jump scale for Gen5-7).

v2: Make the helper a static inline defined in brw_eu.h, instead of
    an actual function in brw_eu_emit.c (as suggested by Matt).

i965: Don't check for format differences when using the blorp blitter

Previously the blorp blitter wouldn't be used if the source and destination
buffer had a different format other than swizzling between RGB and BGR and
adding or removing a dummy alpha channel. However there's no reason why the
blorp code path can't be used to do almost all format conversions so this
patch just removes the checks. However it does explicitly disable converting
to/from MESA_FORMAT_Z24_UNORM_X8_UINT because there is a similar check
brw_blorp_copytexsubimage.

This doesn't cause any Piglit test regressions at least on Ivybridge.
