Remove support for LLVM 12

We can now build with LLVM 14 and no longer need to keep LLVM 12 patches
and compatibility code.

-Subject: [PATCH] Avoid calling ParseCommandLineOptions in BackendUtil if
- possible
-
-Calling `ParseCommandLineOptions` should only be called from `main` as the
-CommandLine setup code isn't thread-safe. As BackendUtil is part of the
-generic Clang FrontendAction logic, a process which has several threads executing
-Clang FrontendActions will randomly crash in the unsafe setup code.
-
-This patch avoids calling the function unless either the debug-pass option or
-limit-float-precision option is set. Without these two options set the
-`ParseCommandLineOptions` call doesn't do anything beside parsing
-the command line `clang` which doesn't set any options.
-
-See also D99652 where LLDB received a workaround for this crash.
