  -----------
  [BasicAA] Move more extension logic into ExtendedValue (NFC)

Add methods to appropriately extend KnownBits/ConstantRange there,
same as with APInt. Also clean up the known bits handling by
actually doing that extension rather than checking ZExtBits. This
doesn't matter now, but becomes relevant once truncation is
involved.
