Since 624e799cc3 ("nir: Drop nir_ssa_def::name and nir_register::name"), SSA
defs don't have names, making the name argument unused. Drop it from the
signature and fix the call sites. This was done with the help of the following
Coccinelle semantic patch:
@@
expression A, B, C, D, E;
@@
-nir_ssa_dest_init(A, B, C, D, E);
+nir_ssa_dest_init(A, B, C, D);

While this change helps with few shaders, the main benefit is
that it allows to unroll loops comming from nine+ttn on vec4
backends. D3D9 REP ... ENDREP type loops are unrolled now already,
LOOP ... ENDLOOP need some nine changes that will come later.
