Enable ILP scheduling for all nodes by default on PPC.
Over the entire test-suite, this has an insignificantly negative average performance impact, but reduces some of the worst slowdowns from the anti-dep. change (r158294). Largest speedups: SingleSource/Benchmarks/Stanford/Quicksort - 28% SingleSource/Benchmarks/Stanford/Towers - 24% SingleSource/Benchmarks/Shootout-C++/matrix - 23% MultiSource/Benchmarks/SciMark2-C/scimark2 - 19% MultiSource/Benchmarks/MiBench/automotive-bitcount/automotive-bitcount - 15% (matrix and automotive-bitcount were both in the top-5 slowdown list from the anti-dep. change) Largest slowdowns: MultiSource/Benchmarks/McCat/03-testtrie/testtrie - 28% MultiSource/Benchmarks/mediabench/gsm/toast/toast - 26% MultiSource/Benchmarks/MiBench/automotive-susan/automotive-susan - 21% SingleSource/Benchmarks/CoyoteBench/lpbench - 20% MultiSource/Applications/d/make_dparser - 16% git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158296 91177308-0d34-0410-b5e6-96231b3b80d8
