We normally don't drop functions from the C API's, but in this case I think we can: * The old implementation of getFileOffset was fairly broken * The introduction of LLVMGetSymbolFileOffset was itself a C api breaking change as it removed LLVMGetSymbolOffset. * It is an incredibly specialized use case. The only reason MCJIT needs it is because of its odd position of being a dynamic linker of .o files. llvm-svn: 206750
