broadcom/vc4: Use the RA callback to improve register selection's choices.

We simply pick r4 if available (anything else would force a MOV), then
round-robin through accumulators (avoids physical regfile RAW delay
slots), then round-robin through the physical regfile.

The effect on instruction count is pretty impressive:

total instructions in shared programs: 76563 -> 74526 (-2.66%)
instructions in affected programs:     66463 -> 64426 (-3.06%)

and we could probably do better with a little heuristic of "if we're going
to choose a physical reg, and other operands of instructions using this as
a src have the same physical regfile, then use the other regfile".

ra: Add a callback for selecting a register from what's available.

VC4 has had a tension, similar to pre-Sandybridge Intel, where we want to
use low-numbered registers (more parallelism on Intel, fewer delay slots
on vc4), but in order to give instruction scheduling the most freedom to
avoid delays we want to round-robin between registers of the same cost.
Our two heuristics so far have chosen one end or the other of that
tradeoff.

The callback, instead, hands the driver the set of registers that are
available, and the driver gets to make its own choice.  This will be used
in vc4 to round-robin between registers of the same cost, and might be
used in the future for improving bank selection.

i965: perf: flush batchbuffers at the beginning of queries

As Chris commented, it makes more sense to have batch buffer flushes
before the query. Usually applications like frame_retrace do a series
of queries and in that case, with flushes at the end of the queries,
we might still have the first query contained in 2 different batchs.
More generally it would be quite usual to have the query contained in
2 batch buffers because we never now what's the fill rate of the
current batch buffer.

If we move the flushing at the beginning of the queries, it's pretty
much guaranteed that queries will be contained in a single batch
buffer (unless the amount of commands is huge, but then it's only fair
to include reloading request times in the measurements).

i965: Enable regular fast-clears (CCS_D) on gen9+

The set of formats which supports CCS_E is actually fairly small on
gen9.  However, everything that supports fast-clears on gen8 also
supports fast-clears on gen9+.  The one very annoying exception is
that blending is broken for non-0/1 clear colors with sRGB formats.
In order to solve that problem, we do a resolve to get rid of the
clear color.  Another option would be to just not fast-clear with
non-0/1 clear colors however non-0/1 + blending + sRGB is uncommon
enough that this shouldn't be a significant performance problem.

This appears to help gl_manhattan31_off by about 2%.
