* PowerPC NCG: support conditional branches outside +-32KB
Work around the PowerPC architecture's +-32KB limitation for conditional
branches by conditionally skipping an unconditional branch instead
(unconditional branches have a +-32MB range).
This requires an extra pass over the basic blocks for each CmmTop after
block sequencing, to determine which branches are "far".
Fixes ticket #709, "Fixup too large" error with -fasm on PowerPC
