This patch aligns the behaviour of computeCalleeSaveRegisterPairs,
which calculates the offset at which the predicate CSR is stored
within the callee-saves, with that of determineSVEStackObjectOffsets,
which calculates the offsets of all objects, including the callee-saves.
This change is needed to make sure the actual offset corresponds to
the info used for e.g. unwind call frame instructions.
