4f4e1e5ed9 nir: Add flag to tex instruction to indicate lowering cube to array
E.g. r600 a cube texture lookup uses a specific cube instruction
to evaluate the sample coordinates and the face ID, so that the cube
texture lookup can be lowered to a array texture lookup, thereby sharing
the code with the 2D array texture lopkup.
However, for TXD the given gradients still need to be three-component
vectors, so add a flag that the NIR validation knows that we deal with
cube texture that was lowered to an array and can validate accordingly.

v2: Handle new flag in serialization (Marek)
v3: Rebase so that the change does not require the patch to deduct the
    number of offset and grad components from sampler type

f064b7a42c nir: Add some ssa-only fast-paths for nir_src rewrite
Basically every pass in NIR uses nir_ssa_def_rewrite_uses which calls
nir_instr_rewrite_src which is fairly complex because it handles all
sorts of non-SSA cases.  Since we already know a priori that every
source written by nir_ssa_def_rewrite_uses is SSA, we can check new_src
once at the top of the function and cut out all that complexity.

While we're at it, we expose a new SSA-only nir_ssa_def_rewrite_uses_ssa
helper which takes an SSA def which avoids the one SSA check.  It's also
more convenient 90% of the time.

4099cdc97f compiler/nir: Add support for lowering stores with nir_lower_instruction
The function is very convenient for lowering any type of instruction
that can be easily filtered, but so far instructions that didn't return
a value were siletly ignored.

Fix this by
  - not requiring a return value in the instruction
  - add a new special return value from the lowering implementation
    function to indicated that an instruction that doesn't have a
    return value must be removed, and
  - don't try to collect and replace uses in this case.

24669a672f nir: Add a printf lowering pass (v5)
This pass creates a SSBO var for the printf buffer. It does an atomic increment
at the beginning of the buffer to determine where to write, then dumps
the args after that.

v2: [airlied]
Enhanced to use an index into a set of format info that is passed
back to the caller. The format info contains the number of args,
argument sizes and the format string.

v3: move format string lowering to vtn

v4: Jason reworked it.

v5: assume buffer has initial offset prebaked in and work from there.

d3d28f6c2d nir: Redefine start/end_ip of blocks to fix NIR-to-TGSI liveness bugs.
With the block's end_ip accidentally being the ip of the next instruction,
contrary to the comment, you would end up doing end-of-block freeing early
and have the value missing when it came time to emit the next instruction.
Just expand the ips to have separate ones for start and end of block --
while it means that nir_instr->index is no longer incremented by 1 per
instruction, it makes sense for use in liveness because a backend is
likely to need to do other things at block boundaries (like emit the if
statement's code), and having an ip to identify that stuff is useful.

Fixes: a206b58157 ("nir: Add a block start/end ip to live instr index metadata.")
