  Log Message:
  -----------
  [AMDGPU] Allow some modifiers on VOP3B instructions

V_DIV_SCALE_F32/F64 are VOP3B encoded so they can't use the ABS src
modifier, but they can still use NEG and the usual output modifiers.

This partially reverts 3b99f12a4e6f "AMDGPU: Remove modifiers from v_div_scale_*".
