Change subject: IMPALA-14760: Add Clang 12 for compilation ...................................................................... IMPALA-14760: Add Clang 12 for compilation Impala's dependency on LLVM is very performance sensitive, but we also use Clang for sanitizer builds. In that context, our old version of Clang has been causing issues compiling new dependencies (e.g. IMPALA-13190 for roaring bitmap, IMPALA-14092 for Paimon's use of Arrow). This adds a build of LLVM 12 to provide a newer Clang for our sanitizer builds. This includes LLD in the build, which may be useful as an alternative linker. This does a lot of changes to the structure of the LLVM build scripts. It adds an ability to build with PGO (which is not used for this change). It also changes the LLVM build to use ninja to limit link concurrency.
