Module Debugging: Emit debug type information into clang ObjC modules. When -fmodule-format is set to "obj", emit debug info for all types declared in a module or referenced by a declaration into the module's object file container. This patch adds support for Objective-C types and methods. llvm-svn: 247068

DebugInfo: Make DICompositeTypes distinct most of the time Since elements of most kinds of DICompositeType have back references, most are involved in uniquing cycles. Except via the ODR 'identifier:' field, which doesn't care about the storage type (see r266549), they have no hope of being uniqued. Distinct nodes are far more efficient, so use them for most kinds of DICompositeType definitions (i.e., when DIType::isForwardDecl is false). The exceptions: - DW_TAG_array_type, since their elements never have back-references and they never have ODR 'identifier:' fields; - DW_TAG_enumeration_type when there is no ODR 'identifier:' field, since their elements usually don't have back-references. This breaks the last major uniquing cycle I'm aware of in the debug info graph. The impact won't be enormous for C++ because references to ODR-uniqued nodes still use string-based DITypeRefs; but this should prevent a regression in C++ when we drop the string-based references. This wouldn't have been reasonable until r266549, when composite types stopped relying on being uniqued by structural equivalence to prevent blow-ups at LTO time. llvm-svn: 266556
