Hal Finkel 091acf253b [PowerPC] Mark jumps as expensive (using using CR bits) 
On PowerPC, which has a full set of logical operations on (its multiple sets
of) condition-register bits, it is not profitable to break of complex
conditions feeding a jump into multiple jumps. We can turn off this feature of
CGP/SDAGBuilder by marking jumps as "expensive".

P7 test-suite speedups (no regressions):
MultiSource/Benchmarks/FreeBench/pcompress2/pcompress2
	-0.626647% +/- 0.323583%
MultiSource/Benchmarks/Olden/power/power
	-18.2821% +/- 8.06481%
