See issue #64166 for more information about the layering issue. The PPCMCTargetDesc library was including CodeGen headers such as PPCInstrInfo.h and calling inline functions in them. This doesn't work in the Bazel build, and is error-prone. If the inline function moves to a cpp file, it will result in linker errors. To address the issue, I moved several inline functions to PPCMCTargetDesc.cpp, and declared them in the PPC namespace in PPCMCTargetDesc.h, which seemed like the most straightforward fix.
