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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206750 91177308-0d34-0410-b5e6-96231b3b80d8
