Recent changes make two other smaller shared adaptions necessary
for the ppc port:

First, introduce replacement variable $$CondRegister in adl.

Further, the latest changes to compressed klasses broke an
optimization on ppc.  This change contains a better way
to check for the max size of a compressed klass.  I need not mask
sign extension bits if compressed klasses are at most 31 bits.

Please review and test this change.

Best regards,
