Commit abfe348e6b4c50c750d70adcf0b99fd3d8d4132e by i [test] Improve CodeGenCXX/difile_entry.cpp The test added in D87147 did not actually test PR47391. Use an absolute path to test the canonicalization.

Commit 8e8d214c4a6c417e42996faeb9211a5c2e32111f by lebedev.ri [NFCI][SimplifyCFG] Prefer to add Insert edges before Delete edges into DomTreeUpdater, if reasonable This has a measurable impact on the number of DomTree recalculations. While this doesn't handle all the cases, it deals with the most obvious ones.

Commit 894d2dbf502026a2b063340f8214b8ffd7cf7e21 by tianshilei1992 [LLVM] Added OpenMP to `LLVM_ALL_RUNTIMES` This patch added `openmp` to `LLVM_ALL_RUNTIMES` so that when the CMake argument `LLVM_ENABLE_RUNTIMES=all`, OpenMP can also be built.

Commit 7be3285248bf54d0784a76174cf44cf7c1e780a5 by tianshilei1992 [OpenMP] Not set OPENMP_STANDALONE_BUILD=ON when building OpenMP along with LLVM For now, `*_STANDALONE_BUILD` is set to ON even if they're built along with LLVM because of issues mentioned in the comments. This can cause some issues. For example, if we build OpenMP along with LLVM, we'd like to copy those OpenMP headers to `<prefix>/lib/clang/<version>/include` such that `clang` can find those headers without using `-I <prefix>/include` because those headers will be copied to `<prefix>/include` if it is built standalone. In this patch, we fixed the dependence issue in OpenMP such that it can be built correctly even with `OPENMP_STANDALONE_BUILD=OFF`. The issue is in the call to `add_lit_testsuite`, where `clang` and `clang-resource-headers` are passed as `DEPENDS`. Since we're building OpenMP along with LLVM, `clang` is set by CMake to be the C/C++ compiler, therefore these two dependences are no longer needed, where caused the dependence issue.
