freedreno/ir3: handle const/immed/abs/neg in cp

Be smarter about propagating copies from const or immed, or with abs/neg
modifiers.  Also, realize that absneg.s and absneg.f are really "fancy"
mov instructions.

This opens up the possibility to remove more copies.  It helps the TGSI
frontend a bit, but will be really needed for the NIR f/e which builds
everything up in SSA form (ie. will *always* insert a mov from const or
immediate).
