Some targets like microMIPS and ARM Thumb use the last bit of a symbol's value to mark 'compressed' code. This patch adds new virtual function `DynamicTable::getAtomVirtualAddress` which allows to adjust a symbol's value before using it in a dynamic table tags like DT_INIT / DT_FINI. llvm-svn: 223963
