  • the opcodes return true iff at least one element(testAny) or all
    elements(testALL) of the vecror mask are true
  • both testAny and testAll opcodes have masked and non-masked
    versions, so add mTestAny, mTestAll, mmTestAny, mmTestAll

I think we need a flag to indicate that this operation is on a mask, under a mask

Added ILProp1::VectorMasked property. But after some thought, not sure about "on mask" property. Usually we check the return type of the opcode vs the type of any of its children. Do you think we need that flag? @BradleyWood

You're right, its not necessary. I leave it up to you

Do we need a flag to indicate these operations are on a mask (not under a mask)?

Fixed a bug in getVectorOperation().
