Clang provides the `-mlink-bitcode-file` and `-mlink-builtin-bitcode` options to insert LLVM-IR into the current TU. These are usefuly primarily for including LLVM-IR files that require special handling to be correct and cannot be linked normally, such as GPU vendor libraries like `libdevice.10.bc`. Currently these options can only be used if the source input goes through the AST consumer path. This patch makes the changes necessary to also support this when the input is LLVM-IR. This will allow the following operation: ``` clang in.bc -Xclang -mlink-builtin-bitcode -Xclang libdevice.10.bc ``` Reviewed By: yaxunl Differential Revision: https://reviews.llvm.org/D152391
