Changes

Summary

1. [DAGCombine] Do not try to deduplicate commutative operations if both operand are the same. Summary: It is creating useless work as the commuted nodes is the same as the node we are working on in that case. Reviewers: jyknight, nemanjai, mkuper, spatel, RKSimon, zvi, bkramer Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D33840
2. clang-format: Fix left pointer alignment after delctype/typeof Change 272124* introduced a regression in spaceRequiredBetween for left aligned pointers to decltype and typeof expressions. This fix adds logic to fix this. The test added is based on a related test in determineStarAmpUsage. Also add test cases for the regression. http://llvm.org/viewvc/llvm-project?view=revision&revision=272124 LLVM bug tracker: https://bugs.llvm.org/show_bug.cgi?id=30407 Differential revision: https://reviews.llvm.org/D35847 Fix contributed by euhlmann!
3. Add braces to silence gcc dangling-else warnings. NFCI.
4. Set the lexical context for dummy tag decl inside createTagFromNewDecl This is a follow-up to r310706. This change has been recommended by Bruno Cardoso Lopes and Richard Smith.
5. [SelectionDAG] combine vextract (v1iX extract_subvector(vNiX, Idx)) into vextract(vNiX,Idx) when creating vextract with getNode(). This case appeared in AVX512 after fixing pr33349 in r310552. Differential revision: https://reviews.llvm.org/D36571
