freedreno/ir3: set dst type of alu instructions correctly.
Though it should be fixed in RA pass, it needs to be set correctly from
the beginning according to the bitsize of NIR dest.
v2: Would be better for mad,fddx,fddy to fixup later in RA pass.
[small cleanup of fallout from imov/fmov removal fallout]
