I feel so dirty. But this will let the IR be a lot more flexible seeing
as we really are vector in a certain sense (I/O, small types)

We'd really rather not emit extracts. We are approaching on a vector IR
anyway which is annoying but really necessary to handle I/O and fp16
correctly. So let's just go all the way and deal with swizzles and masks
within reason; it'll still be somewhat saner in the long-term.

In the second (scalar pass) use the information about # of registers
used in the first pass as the target max, and round-robin within that
range. This generally gives the post-RA sched pass more opportunities
to re-order instructions to remove nop's.
Also, we can be a bit clever when assigning dest registers for SFU
instructions, by picking the register used for it's src (if available
and already assigned). This avoids some (ss) syncs caused by write
after read hazards. (Ie. the SFU instruction will read it's own src
before writing dest.)

Add a parameter so the callback can know which node it is selecting a
register for. And remove the graph parameter, as it is unused by
existing users, and somewhat unnecessary (ie. the callback data could
be used instead).
And add a comment so $future_me remembers how this works.

Doesn't take into account stalls that result from a register written in
a different block, etc. But this should be more useful than just using
number of (ss)'s by trying to estimate how costly a given sync is.

They were inserting a nop between back to back SFU instrucions. But

The vertex array object contains 32 vertex arrays. By that we cannot
reference more then these in the vertex shader inputs. So, we can use
the 32 bits u_bit_scan function to iterate the vertex shader inputs
and place an assert that only these are present. Also place an other
assert that the vertex array setup in i965 does not overrun the
enabled array in brw_context:🆚:enabled.
