st/mesa: Treat vertex inputs absent in inputMapping as zero in mesa_to_tgsi

After updating vertex inputs being read based on optimized NIR, they may go out
of sync with inputs in mesa IR. Which is translated to TGSI and used together
with NIR if draw doesn't have llvm.

It's much easier to treat such inputs as zero because there is no pass to
entirely get rid of them and they don't contribute to shader's output.

etnaviv: Fix depth stencil ops on GC880/GC2000

This patch fixes depth stencil ops on MX6S GC880 and MX6Q GC2000.
The following dEQPs now pass:
  dEQP-GLES2.functional.fragment_ops.depth_stencil.stencil_depth_funcs.*
  dEQP-GLES2.functional.fragment_ops.depth_stencil.stencil_ops.*
which is roughly 600 fixed dEQP tests.

The problem is that if the front-facing stencil has a value mask 0x00 and
the back-facing stencil has some non-zero value mask, then the stencil part
of the depth stencil buffer is written with 0x00 unconditionally. The blob
replicates the value mask of the back-facing stencil to the value mask of
the front-facing stencil to achieve correct rendering, replicate the same
behavior here.

spirv: Rewrite CFG construction

This commit completely rewrites the way we extract a structured CFG from
SPIR-V.  The new approach is different in a few ways:

 1. It does a breadth-first search instead of depth-first.  This means
    that we've visited the merge node for a construct before we visit
    any of the nodes inside the construct.  This makes it easier to
    validate things like loop and switch nesting.

 2. We record more information in the CFG.  Earlier commits added a
    parent pointer to vtn_cf_node but we now record all of the merge and
    other special blocks for each CFG node.  This lets us validate
    things more precisely.

 3. It makes heavy use of merge blocks for walking the CFG.  Previously,
    we sort of used them as hints for trying to guess the CFG structure
    but things got dicey whenever a merge was missing.  We had some
    heuristics for how to handle short-circuiting if statements but it
    was a bunch of special cases.

    Now, we make them a fundamental part of walking the CFG.  When we
    encounter a control-flow construct, we add the body components of
    the construct to the BFS work list and then jump to the merge block
    if one exists to continue scanning the current CFG nesting level.
    If no merge block exists, we assume that means that control-flow
    never re-converges in a normal way and that the only way to get back
    to normality is with a direct jump such as a loop break or continue.
    This should make things far more robust when trying to deal with the
    more creative placement (or lack thereof) of merge instructions.
