Fix CLANG_BOOTSTRAP_TARGETS in Release.cmake

[kwk]

Problem

Before this patch you could not build the stage2-LLVM for example because you first had to manually add it to CLANG_BOOTSTRAP_TARGETS in the Release.cmake and also add it to LLVM_RELEASE_FINAL_STAGE_TARGETS in the cmake configure run. Now you can just use -DLLVM_RELEASE_FINAL_STAGE_TARGETS="LLVM;clang" on the cmake CLI and be able to build the targets stage2-LLVM and stage2-clang without further changes to the cache file.

Solution

Take all LLVM_RELEASE_FINAL_STAGE_TARGETS elements and append them prefixed with stage2- to CLANG_BOOTSTRAP_TARGETS. Afterwards all duplicates are removed.
