13acbaecd8 radeonsi: rewrite the prefix sum computation for shader culling 
Instead of storing the vertex mask per wave into LDS and then computing
the prefix sum, store 8-bit bitcounts (vertex counts) of the vertex masks
into LDS. This allows us to compute the sum using v_sad_u8, which computes
a sum of 4 i8vec4 components in one instruction.

Each i8vec4 of vertex counts is loaded in parallel threads (one dword
per thread) instead of all being loaded in thread 0, and readlane copies
them to SGPRs instead of readfirstlane.

LDS is no longer initialized before culling. Instead, the counts for
inactive waves are masked with AND later.

Incorrect old comments are also fixed.

This change removes 80 bytes from the code size, and it allows increasing
the workgroup size from 128 to 256. (which is the main motivation for this)

Now changing the workgroup size with wave64 has no effect on the code size.
Switching to wave32 with 8 waves even generates slightly smaller code than
wave64 with 4 waves.

55aeac7af4 ac/nir: implement nir_op_vec5 
Since sparse fetch/load uses vec5 destinations, it may be possible that we
encounter nir_op_vec5.

271dd1837a ac/llvm: insert phis before demote kill 
LLVM (like NIR) requires phi instructions to be before any other
instructions in the block. ac_branch_exited() can insert non-phi
instructions before visit_block() adds phis, so visit_block() should add
phi instructions before the non-phi instructions ac_branch_exited()
inserts.

45524afe95 radv/llvm: implement a workaround for gl_FragCoord.z with VRS on GFX10.3 
Without it, FragCoord.z will have the value of one of the fine pixels
instead of the center of the coarse pixel.

It's only enabled for RADV.

d7ee265a95 ac,radeonsi: fix load_first_vertex 
GL doesn't use it, so this change is not necessary, but it's better
this way.

There is also a small cleanup using si_unpack_param.
