Commit 63aeaf754a78c67ca3f8343d525dfb7a378dfa9e by asbirlea [DominatorTree] Add support for mixed pre/post CFG views. Add support for mixed pre/post CFG views. Update usages of the MemorySSAUpdater to use the new DT API by requesting the DT updates to be done by the MSSAUpdater. Differential Revision: https://reviews.llvm.org/D93371

Commit 41d919aa29468ac072755b8449b8a38ff26f6979 by riddleriver [mlir][TypeDefGen] Remove the need to define parser/printer for singleton types This allows for singleton types without an explicit parser/printer to simply use the mnemonic as the assembly format, removing the need for these types to provide the parser/printer fields.

Commit b37de2afa30fe4312aa9b87b11208bd7e05c8fa1 by Jonas Devlieghere [Support] Untie the llvm::Signpost interface from llvm::Timer Make llvm::Signpost more generic by untying from llvm::Timer. This allows signposts to be used in a different context. My motivation for doing this is being able to use signposts in LLDB. Differential revision: https://reviews.llvm.org/D93655

Commit 6d94eeadd28af4d488b5875778a3ebfa0d749b52 by Jonas Devlieghere [lldb] Ad os_signpost support to lldb_private::Timer Emit os_signposts when supported from LLDB's timer class. A vast amount of performance sensitive places in LLDB are already instrumented with the Timer class. By emitting signposts we can examine this information in Instruments. I recommend looking at Daniel's differential for why this is so powerful: https://reviews.llvm.org/D52954. Differential revision: https://reviews.llvm.org/D93657
