mesa: fix display list corner case assertion

This fixes a failed assertion in glDeleteLists() for the following
case:

list = glGenLists(1);
glDeleteLists(list, 1);

when those are the first display list commands issued by the
application.

When we generate display lists, we plug in empty lists created with
the make_list() helper.  This function uses the OPCODE_END_OF_LIST
opcode but does not call dlist_alloc() which would set the
InstSize[OPCODE_END_OF_LIST] element to non-zero.

When the empty list was deleted, we failed the InstSize[opcode] > 0
assertion.

Typically, display lists are created with glNewList/glEndList so we
set InstSize[OPCODE_END_OF_LIST] = 1 in dlist_alloc().  That's why
this bug wasn't found before.

To fix this failure, simply initialize the InstSize[OPCODE_END_OF_LIST]
element in make_list().

v3d: Rematerialize MOVs of uniforms instead of spilling them.

If we have a MOV of a uniform value available to spill, that's one of our
best choices.  We can just not spill the value, and emit a new load of the
uniform as the fill.  This saves bothering the TMU and the thrsw, and is
the same cost in uniforms (since the spill offset is a uniform anyway).

This doesn't have a huge impact on shader-db, since there aren't a whole
lot of spills and we usually copy-prop the uniforms at the VIR level such
that the only uniform MOVs are from vir_lower_uniforms:

total instructions in shared programs: 6430292 -> 6430279 (<.01%)
total uniforms in shared programs: 2386023 -> 2385787 (<.01%)
total spills in shared programs: 4961 -> 4960 (-0.02%)
total fills in shared programs: 6352 -> 6350 (-0.03%)

However, I'm interested in dropping the uniforms copy-prop in the backend,
since it would be cheaper to not load repeated uniforms if we have the
registers to spare.  This also saves many spills on
dEQP-GLES31.functional.ubo.random.all_per_block_buffers.20, which is what
motivated a bunch of my recent backend work in the first place:

before: 46 spills, 106 fills, 3062 instructions
after: 0 spills, 0 fills, 2611 instructions

v3d: Dump the VIR after register spilling if we were forced to.

Spilling is unusual, but one often has to debug it when it happens, so
dump it.

v3d: Fix vir_is_raw_mov() for input unpacks.

There are no users at the moment, but I wanted to start using this in
register spilling.

st/mesa: Reduce array updates due to current changes.

Since using bitmasks we can easily check if we have any
current value that is potentially uploaded on array setup.
So check for any potential vertex program input that is not
already a vao enabled array. Only flag array update if there is
a potential overlap.
