[PPC] Enable transformations in PPCPassConfig::addIRPasses at O2 http://reviews.llvm.org/D18562 A large number of testcases has been modified so they pass after this test. One testcase is deleted, because I realized even after undoing the original change that was committed with this testcase, the testcase still passes. So I removed it. The change to one other testcase (test/CodeGen/PowerPC/pr25802.ll) is an arbitrary change to keep it passing. Given the original intention of the testcase, and the fact that fixing it will require some time to change the testcase, we concluded that this quick change will be enough. llvm-svn: 265683
