Reland "[CodeGen] Keep track info of lazy-emitted symbols in ModuleBuilder"
This reverts commits: d3ddc251 d90eecff This relands below commit with asan fix: The intent of this patch is to selectively carry some states over to the Builder so we won't lose the information of the previous symbols. This used to be several downstream patches of Cling, it aims to fix errors in Clang Interpreter when trying to use inline functions. Before this patch: clang-repl> inline int foo() { return 42;} clang-repl> int x = foo(); JIT session error: Symbols not found: [ _Z3foov ] error: Failed to materialize symbols: { (main, { x, $.incr_module_1.__inits.0, __orc_init_func.incr_module_1 }) } Co-authored-by:Axel Naumann <Axel.Naumann@cern.ch> Signed-off-by:
