Summary: To allow the development of future instrumentation work, this patch adds support in BOLT for linking arbitrary libraries into the binary processed by BOLT. We use orc relocation handling mechanism for that. With this support, this patch also moves code programatically generated in X86 assembly language by X86MCPlusBuilder to C code written in a new library called bolt_rt. Change CMake to support this library as an external project in the same way as clang does with compiler_rt. This library is installed in the lib/ folder relative to BOLT root installation and by default instrumentation will look for the library at that location to finish processing the binary with instrumentation.
