Large code model support for PowerPC.
Large code model is identical to medium code model except that the
addis/addi sequence for "local" accesses is never used. All accesses
use the addis/ld sequence.
The coding changes are straightforward; most of the patch is taken up
with creating variants of the medium model tests for large model.
