Alyssa Rosenzweig a6123a80da nir/opt_shrink_vectors: shrink some intrinsics from start
If the backend supports it, intrinsics with a component() are straightforward to
shrink from the start. Notably helps vectorized I/O.

v2: add an option for this and enable only on grown up backends, because some
backends ignore the component() parameter.

Faith Ekstrand 4695bebc79 nir: Drop nir_dest
Instead, we replace every use of it with nir_def.  Most of this commit
was generated by sed:

   sed -i -e 's/dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp

A few manual fixups were required in lima and the nir_legacy code.

Faith Ekstrand d2c4749986 nir: Drop more instances of nir_ssa_dest_init()
Catching the cases that Coccinelle missed.  Mostly in C++ files using
gtest which causes Coccinelle to just give up and walk away.

Alyssa Rosenzweig 01e9ee79f7 nir: Drop unused name from nir_ssa_dest_init
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);

Pavel Ondračka 94eff7ccd8 nir: shrink phi nodes in nir_opt_shrink_vectors
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.
