freedreno/a3xx/compiler: fix CMP

The 1st src to add.s needs (r) flag (repeat), otherwise it will end up:

  add.s dst.xyzw, tmp.xxxx -1

instead of:

  add.s dst.xyzw, tmp.xyzw, -1

Also, if we are using a temporary dst to avoid clobbering one of the src
registers, we actually need to use that as the dst for the sel
instruction.

freedreno/a3xx/compiler: handle saturate on dst

Sometimes things other than color dst need saturating, like if there is
a 'clamp(foo, 0.0, 1.0)'.  So for saturated dst add the extra
instructions to fix up dst.

freedreno/a3xx/compiler: use max_reg rather than file_count

Our current (rather naive) register assignment is based on mapping
different register files (INPUT, OUTPUT, TEMP, CONST, etc) based on the
max register index of the preceding file.  But in some cases, the lowest
used register in a file might not be zero.  In which case
file_count[file] != file_max[file] + 1.

freedreno/a3xx/compiler: cat4 cannot use const reg as src

Category 4 instructions (rsq, rcp, sqrt, etc) seem to be unable to take
a const register as src.  In these cases we need to move the src to a
temporary gpr first.

This is the second case of such a restriction, where the instruction
encoding appears to support a const src, but in fact the hw appears to
ignore that bit.  So split things out into a helper that can be re-used
for any instructions which have this limitation.

freedreno/a3xx/compiler: make compiler errors more useful

We probably should get rid of assert() entirely, but at this stage it is
more useful for things to crash where we can catch it in a debugger.
With compile_error() we have a single place to set an error flag (to
bail out and return an error on the next instruction) so that will be a
small change later when enough of the compiler bugs are sorted.

But re-arrange/cleanup the error/assert stuff so we at least get a dump
of the TGSI that triggered it.  So we see some useful output in piglit
logs.

freedreno/a3xx/compiler: bit of re-arrange/cleanup

It seems there are a number of cases where instructions have limitations
about taking reading src's from const register file, so make
get_unconst() a bit easier to use.

freedreno/a3xx/compiler: fix SGT/SLT/etc

The cmps.f.* instruction doesn't actually seem to give a float 1.0 or
0.0 output.  It either needs a cov.u16f16 or add.s + sel.f16.  This
makes SGT/SLT/etc more similar to CMP, so handle them in trans_cmp().

This fixes a bunch of piglit tests.

nouveau/video: avoid overwriting base codec init with template

Commit 53e20b8b introduced the use of a template to initialize some
common fields. Move this copying of fields to before the common vp3
fields are initialized.

mesa: Set query->EverBound in glQueryCounter().

glIsQuery is supposed to return false for names returned by glGenQueries
until their first use.  BeginQuery is a use, but QueryCounter is also a
use.

From the ARB_timer_query spec:
"A timer query object is created with the command

      void QueryCounter(uint id, enum target);

 [...] If <id> is an unused query object name, the
 name is marked as used [...]"

Fixes Piglit's spec/ARB_timer_query/query-lifetime.
