Patch 1/4 adding bitcode support. Store whether or not a function is using Key Instructions in its DISubprogram so that we don't need to rely on the -mllvm flag -dwarf-use-key-instructions to determine whether or not to interpret Key Instructions metadata to decide is_stmt placement at DWARF emission time. This makes bitcode support simple and enables well defined mixing of non-key-instructions and key-instructions functions in an LTO context. This patch adds the bit (using DISubprogram::SubclassData1). PR 144104 and 144103 use it during DWARF emission. PR 44102 adds bitcode support. See pull request for overview of alternative attempts.
