Flip the new block-placement pass to be on by default. This is mostly to test the waters. I'd like to get results from FNT build bots and other bots running on non-x86 platforms. This feature has been pretty heavily tested over the last few months by me, and it fixes several of the execution time regressions caused by the inlining work by preventing inlining decisions from radically impacting block layout. I've seen very large improvements in yacr2 and ackermann benchmarks, along with the expected noise across all of the benchmark suite whenever code layout changes. I've analyzed all of the regressions and fixed them, or found them to be impossible to fix. See my email to llvmdev for more details. I'd like for this to be in 3.1 as it complements the inliner changes, but if any failures are showing up or anyone has concerns, it is just a flag flip and so can be easily turned off. I'm switching it on tonight to try and get at least one run through various folks' performance suites in case SPEC or something else has serious issues with it. I'll watch bots and revert if anything shows up. llvm-svn: 154816

[DAGCombiner] extend(ifpositive(X)) -> shift-right (not X) This is almost the same as an existing IR canonicalization in instcombine, so I'm assuming this is a good early generic DAG combine too. The motivation comes from reduced bit-hacking for select-of-constants in IR after rL331486. We want to restore that functionality in the DAG as noted in the commit comments for that change and the llvm-dev discussion here: http://lists.llvm.org/pipermail/llvm-dev/2018-July/124433.html The PPC and AArch tests show that those targets are already doing something similar. x86 will be neutral in the minimal case and generally better when this pattern is extended with other ops as shown in the signbit-shift.ll tests. Note the asymmetry: we don't include the (extend (ifneg X)) transform because it already exists in SimplifySelectCC(), and that is verified in the later unchanged tests in the signbit-shift.ll files. Without the 'not' op, the general transform to use a shift is always a win because that's a single instruction.
