1.0.24.35: Flag-setting VOPs on x86[-64] and conditional moves

 * Most :CONDITIONAL VOPs only specify which condition flags they set

 * GENERIC-{EQL,=,<,>} are :CONDITIONAL VOPs, but don't show up as
   calls anymore

 * Values may be selected with CMOVcc if applicable (and :CMOV is
   in *backend-subfeatures*, for x86):
    - Values that are represented, unboxed, in GPRs are CMOVed using
      custom VOPs
    - Unboxed float and complex types aren't converted
    - Other types are assumed to be boxed and CMOVed as descriptors

 * A test to try and to cover an interesting cross-section of flags
   and values to move conditionally.
