nir/gcm: allow derivative dependent intrinisics to be moved earlier

We can't move them later as we could move them into non-uniform
control flow, but moving them earlier should be fine.

This helps avoid a bunch of spilling in unigine shaders due to
moving the tex instructions sources earlier (outside if branches)
but not the instruction itself.

nir/gcm: Delete dead instructions

Classically, global code motion is also a dead code pass.  However, in
the initial implementation, the decision was made to place every
instruction and let conventional DCE clean up the dead ones.  Because
any uses of a dead instruction are unreachable, we have no late block
and the dead instructions are always scheduled early.  The problem is
that, because we place the dead instruction early, it  pushes the
placement of any dependencies of the dead instruction earlier than they
may need to be placed.  In order prevent dead instructions from
affecting the placement of live ones, we need to delete them.

ir3/ra: Fix off-by-one issues with live-range extension

The intersects() function assumes that inside each instruction values
always die before they are defined, so that if the end of one range is
the same instruction as the beginning of the next then they don't
intersect. However, this isn't the case for values that become live at
the beginning of a basic block, which become live *before* the first
instruction, or instructions that die at the end of a basic block which
die after the last instruction.

For example, imagine that we have two values, A which is defined earlier
in the block and B which is defined in the last instruction of the block
and both die at the end of the basic block (e.g. are used in the next
iteration of a loop). We would compute a range for A of, say, (10, 20)
and for B of (20, 20) since each block's end_ip is the same as the ip of
the last instruction, and RA would consider them to not interfere.
There's a similar problem with values that become live at the beginning.

The fix is to offset the block's start_ip and end_ip by one so that they
don't correspond to any actual instruction. One way to think about this
is that we're adding fake instructions at the beginning and end of a
block where values become live & die. We could invert the order, so that
values consumed by each instruction are considered dead at the end of
the previous instruction, but then values that become dead at the
beginning of the basic block would incorrectly have an empty live range,
with a similar problem at the end of the basic block if we try to say
that values are defined at the beginning of the next instruction. So
the extra padding instructions are unavoidable.

This fixes an accidental infinite loop in the shader for
dEQP-VK.spirv_assembly.type.scalar.u32.switch_vert.

This also makes spirv_to_nir a bit simpler because the new
nir_vector_insert helper automatically handles a constant component
selector like nir_vector_extract does.

st/mesa: Update shader info of ffvp/ARB_vp after translation to NIR

We must update stp->Base.info after translation and before

may become outdated after NIR optimization passes.

anv: Emit pushed UBO bounds checking code in the back-end compiler

This commit fixes performance regressions introduced by e03f9652801ad7
in which we started bounds checking our push constants.  This added a
LOT of shader code to shaders which use the robustBufferAccess feature
and led to substantial spilling.  The checking we just added to the FS
back-end is far more efficient for two reasons:

 1. It can be done at a whole register granularity rather than per-
    scalar and so we emit one SIMD8 SEL per 32B GRF rather than one
    SIMD16 SEL (executed as two SELs) for each component loaded.

 2. Because we do it with NoMask instructions, we can do it on whole
    pushed GRFs without splatting them out to SIMD8 or SIME16 values.
    This means that robust buffer access no longer explodes our register
    pressure for no good reason.

As a tiny side-benefit, we're now using can use AND instead of SEL which
means no need for the flag and better scheduling.

Vulkan pipeline database results on ICL:

    Instructions in all programs: 293586059 -> 238009118 (-18.9%)
    SENDs in all programs: 13568515 -> 13568515 (+0.0%)
    Loops in all programs: 149720 -> 149720 (+0.0%)

    Fills in all programs: 1348397 -> 246061 (-81.8%)
