    amdgcn: Fix v_add constraints (pr112308)

    The instruction doesn't allow "B" constants for the vop3b encoding (used
when
    the cc register isn't VCC), so fix the pattern and all the insns that m=
ight
get
    split to it post-reload.

    Also switch to the new constraint format for ease of adding new
alternatives.
